I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: Lenovo Y50-70 USB 3.0 ports stopped working suddenly

hi haemming,

Welcome to the Forums.

Can you try the following:
1. Boot into the BIOS by continuously tapping F2 on boot-up. Once in the BIOS, hit F9 to load factory default settings then hit F10 to save and exit (this reloads the hardware configuration of the machine). Once inside Windows, uninstall the USB 3,0 driver (Device Manager > Universal Serial Bus Controllers) then scan for hardware changes.

When the USB device comes back, try to test your phone or any USB device (e.g., USB mouse, flashdrive, etc.) and observe.

2. If same problem, try to power down the machine > press the OneKey Recovery button > select System Recovery and test if the mouse will work on the USB 3.0 port
- Sample image

Alternatively, you can also hold the Shift key then restart Windows and observe if the USB mouse will work on the Windows 8 Advanced Options.

If none of the above method works then I recommend you contact the lenovo helpdesk and report your findings as the USB 3.0 port is definitely malfunctioning and requires service.

Let me know how it goes..

I have a Compaq Presario CQ62-215DX, running Norton Internet Security and firewall through Windows 7. I sucessfully installed new Wireless LAN and Lightscribe system software several days ago, along with the Live Essentials, Realtek and Windows 7 Updates.

Everything was operating correctly yesterday, but when I booted up my computer today my wireless mouse refused to work. After trying a fix involving a USB stick, I realized that none of my USB ports work. The ports light up when I restart, until Windows 7 finishes logging in, and once it begins the drivers refuse to work. Is it because of the recent updates? Because I cleaned up my back-up copies? Any help will be apprecited!

A:USB Ports Have suddenly stopped working...

Have you tried disabling and re-enabling all of your USB controllers and ports in Device Manager?

If you don't know how to do get there...
Start menu > Right click on Computer > Manage > Device Manager

Moreover, to disable USB ports, go to the Universal Serial Bus Controllers button in the Device Manager. Right click each individual one and click disable. For each one. Then after each one is disabled, start from the top and do the same thing but click Enable this time. There are some dependencies in there sometimes that will disable more than one individual device, so be aware of that.

Lately every time I try to connect a known working USB device, like digital camera, thumb drive, web cam, etc. I get a pop up window that says the device is not recognized. I have a printer plugged into a USB port, and it works, although I did have to reinstall the driver for it recently, because it too get the same error.
Is there a driver or drivers I should reload? What should I do to determine if it's really a hardware (port) problem? Devices will work on other computers, just not this Compaq desktop, 1.6Ghz, 2GB RAM, roughly 3 years old, XP SP3

That day suddenly my PC's USB ports stopped working. I tried all USB ports with deferent kinds of drives(pendirve, mobile, modem) but computer is not responding. I tried reinstalling my windows 7 but remains same. I also tried Ubuntu, Mint, Hirens Boot CD etc but no OS finds my any kind of USB disc. On windows 7 I tried uninstalling and installing USB drives manually but don't work. In the mean time today at dawn one of my USB modem started working(on Win7) but after some seconds it became like before.

Can anyone figure out which problem I'm facing? Is it related to my hardware?

A:Suddenly all USB ports stopped working on win 7

First place I would start would be update all primary drivers for your PC, what ever flavor you have, desktop/laptop. Go to that vendors website and download and install all the latest drivers. If you have add on specific hardware go to that vendors site for drivers.

The next thing I would do is to rule out any Virus's, malware, spyware and adware that my be lurking about your system. It's known that some of these nasties can and do corrupt system software and hardware.

On a previously fine PC, I noticed the usb cable for my Palm Pilot had fallen out (so that's why I couldn't connect to it!)

So, I foolishly plugged the usb cable in. The screen froze, had to press reset to reboot.

On rebooting my ISDN adaptor had a cross on it, indicating it wasn't enabled, it was IMPOSSIBLE to restart it. So I deleted it in device manager......it wouldn't delete "the device has failed to respond in a timely fashion".

Then I realised all USB connected peripherals were not responding, ie isdn adaptor & printer! Everything I've tried has failed, switched ports, cables, nothing is detected when a usb cable is plugged in. So I was stuck with no internet connection, until I reinstalled my old PCI modem. Please guys, any advice would be much appreciated. I'm concerned something I did plugging that cable in has fried all my usb ports on my mobo

A:USB ports suddenly stopped working!!

Tell us the brand and model of computer, whether a desktop or a laptop, and the location of the usb ports... whether front or back, or whether we are talking about a powered external hub, or a multimedia box in the middle of the computer which has a 9 in 1, 15 in 1, or similar memory card reader with USB ports.
Are the USB ports built into the case, or on a pci card slot on the back of the computer.
Generally, USB ports do not fail. There are a few times when they do because any electronics made with chips, thyristors, and printed circuits can fail. But USB ports are among the most rare of failures... except when you are using multiports.
On inexpensive USB connections, they all share one connector... If you have four or five ports on one connector to the motherboard, then those in use will reduce the power that is accessible on lower quality units.

All the USB Ports were working just fine (two still are, the one with this keyboard and mouse plugged into it.. but I haven't UNPLUGGED them since this problem started so I'm NOT going to do that now, JUST IN CASE, those ports stop working too and then I have absolutely NO ACCESS to my computer at that point. ) and everything was how it normally was.  I had just plugged in a flash drive and removed data from that drive, unplugged it thru the eject button and I also had an external drive plugged in later and it worked and ejected just fine) and then OUT OF NOWHERE now it the USB ports REFUSE to work!
I'll plug in the device, I'll hear the NOISE on the computer that lets you know it's plugged in but then NOTHING happens and it does NOT get recognized in the My Computer/Devices folder!  I have tried ALL the available ports and NONE of them work!  I tried my devices on another computer and they work perfectly fine.  It's THIS computer!  And it's only a year and half old!!!

A:The USB Ports *SUDDENLY* Stopped Working in my De...

Welcome to the Lenovo Community !
I am assuming that the two USB ports that are working are on the back of the computer.  That the two other back ones along with the front ones are not working.  Possibly there is a conflict with the hardware information stored in the CMOS which is preventing all the USB ports from working.  I would suggest you try clearing the CMOS to see if that will correct the problem you are having.  On page #26 of your model's Hardware Maintenance Manual show the location of the coin cell CMOS battery.  The battery's socket will either have a little tab to eject the battery or a slot in which you can use a small screw driver to lightly pry up the edge the battery.  With the machine unplugged remove the battery and press the power button for 15 seconds.  Then reinstall the battery, plug and then boot up the computer to see if the problem is resolved.  It is normal after clearing the CMOS to have to enter the time & date when the computer is booted  up.
The link below is for your model's Hardware Maintenance Manual. When working inside your system please follow all precautions and recommendations that are noted in the manual.

My main desktop which has been going through a bit of a patch at the moment now has all USB ports acting very strangely in that plug something in and the insert sound goes off but nothing shows up in Computer and even Kaspersky does not ask if I want to scan it.

The machine has the usual back and front ports and also a card reader (Icy Box with 2x3.0 and 4x2.0 and SD etc slots)

Now I have tried chkdsk /f /r sfc MBAM SAS ADW full Kaspersky scan and tried the sticks and drive sin my other machines and all are good. Have installed all the drivers etc etc but still no go.

Any ideas please before I run a rescue disk and memtest as I seem to be running out of options. Boards about three years old now - Asus P8Z77-V

A:USB ports suddenly stopped working

Try unplugging all the power and let it sit overnight. Then plug in and try again in the morning. I've seen this work on occasion when all the USB ports suddenly don't work. For that matter, if simply unplugging AC doesn't work, might be worth pulling out any CMOS battery too.

Last night I was doing my usual gaming on my PC when I started getting popups about USB drives malfunctioning. I didn't think much of them at the time. Later on during the night, my USB mouse stopped working. I didn't think much of it and I switched it to a free port. It started working again. Then trouble started.

I plugged my headset into another free port (it had been plugged into my Xbox 360, it was working fine beforehand) and started to watch an episode of a TV show. The sound was horrendous. It wasn't the file and it was not my headset, as I tested it again on my Xbox and was working fine. I switched USB ports. It didn't work. Then my mouse stopped working, and my keyboard. Funnily enough, my USB phone charger still showed it was charging my phone, and it still does right now.

I restarted my computer, and at the POST screen it said a keyboard error had occurred or one was not connected. When I start my computer with the keyboard plugged in, the lights flash and the backlight comes on (it is an illuminated keyboard, so the blue lights beneath the keys work for some reason) but none of the keys registered. I had to dig out an old PS2 keyboard to get my computer to even get past the POST screen.

I did some reading around and saw a simple fix of turning off your computer and unplugging it from all power sources, so I left it unplugged for 10 hours while I was at work with the CMOS battery removed. I got home and plugged it back in with just the keybo... Read more

Hello all,

A Few days ago my laptop stopped reading my 2 USB 2.0 Ports (I am using a Compaq Pressario v6000 Laptop with Vista Home Premium 32bit). I went to the Device Manager and updated, uninstalled, reinstalled, prayed to god yada yada the drivers with no luck. I also went back to a old restore point and no luck with that. My computer is fully updated and I have no other idea's what to do. I have read something about INF files but I am somewhat computer literate (enough to get me in trouble) but not enough to know about INF'S and what to do. Any help would be greatly appreciated, and thanks in advanced for your time.

I have an older Dell Inspiron 5100 that's been rock solid since day one.

I recently transferred all my music from my PC to my Seagate FreeAgent GoFlex so I could organize my files while I was out of town on business. When I got to my hotel and plugged the Seagate into the USB port the laptop would not recognize it.
There's two USB ports, one of the USB ports does nothing at all when I plug the drive in (not even a 'Ding-Dong' sound). The other port at least responds but still not recognized. By "responds" I mean Windows responds with a "Dunn..." sound; not the happy two tone sound of a device actually being recognized and available, just a "Dunn..."

I've used this drive before on this laptop on several occasions so I know it's compatible. I also came home and plugged to drive back into the PC to see if the drive itself responds. It does, and all files are there and happy.

Also, when plugged into the non-responsive USB slot the light on the drive blinks a couple times, the platters spool up for 15 or so seconds then goes out.
When plugged into the other USB slot (the one that goes "Dunn...") the light comes on and stays on and the platters spin untill I unplug the device. But it's still not recognized.

Nothing shows up under the Disc Management tool either.

Normal USB thumb drives work normal still.

Yesterday evening, the USB-C ports of my Lenovo Yoga 920 stopped working suddenly. While working with the computer, the connected external monitor and the laptop screen both went dark and I couldn't revive them by disconnecting/reconnecting any cables or by pressing any keys on the laptop. In the end, I had to force a hard restart of the Yoga 920 by pressing the power button on the right. After rebooting the laptop, I noticed that it completely failed to communicate with any devices connected to the USB-C port, including my external monitor, keyboard, mouse and Ethernet network. First suspecting an issue with the connected USB-C hub (Kensington USB-C Universal Dock 60W (SD4600P)), I performed a full power recycle, including detaching/attaching cables, of all involved components. This had no result. I noticed then in the Windows 10 Device Manager (devmgmt.msc), that the USB device "UCSI USB Connector Manager" was marked as not working (yellow exclamation mark). The status of the device was:This device cannot start. (Code 10) STATUS_DEVICE_POWER_FAILURE Disabling/removing/reinstalling this device in Windows 10 had no effect on the issue. Then I noticed that the laptop didn't charge while connected to the power supply from Lenovo, which was delivered with the laptop. There are two USB-C ports on the left side of the laptop. The one towards the back is marked as the one to use for charging. It didn't work any more. I had to connect the USB-C cable from th...

I have a 32GB USB 3.0 pqi flash drive and it used to work on USB 2.0 ports just fine. I don't know why but it suddenly decided to stop working on USB 2.0 ports (still works on USB 3.0).

USB 2.0 port is not faulty.

How do I get it to work with USB 2.0 again?

A:USB 3.0 pqi flash drive suddenly stopped working on USB 2.0 ports

I would copy the data off and store it someplace if possible. I would take USB 2.0 not working as a warning something may be breaking down in the drive. It might only effect USB 2.0 but it's difficult to be sure.

I'm not a hardware guy so I'm not sure if you can test them with a multi-meter.

Go to Control Panel,click on Hardware and Sound Click on Sound then you devices should come up ; speakers, Digital Audio, and headphones plug your headphones in, then select headphones at the bottom and select set as default option !! then when you disconnect your headphones it automatically switches to the speakers and when you plug them back in it automatically will switch to headphones!!
Hope this helps. Do post back if the issue persists!

Vista Ultimate 64-bit, ASUS Rampage Formula motherboard, USB mouse and keyboard connected in back ports.

Two things happened: Avira antivirus warned me of some threats which I either ignored or deleted. Windows Update had some updates ready (although I'm not sure if it updated).

I turned off my PC for a couple of hours, turned it back on and realized that my USB keyboard was not working on the password screen.

I eventually unplugged it from the back and plugged it into the front, where it worked. However, my USB mouse did not work when plugged into the second front port, nor did it work when plugged into the front port in which the keyboard worked.

I accessed System Restore using my keyboard and restored to one day previously. When it finished, both keyboard and mouse worked, although I got a pop-up message alerting me that the "drivers for your device could not be installed." When I clicked "OK," the mouse stopped working again.

I have checked BIOS and both mouse and keyboard are recognized, so it does not appear to be a hardware issue.

I would go to Device manager and determine which USB 3.0 driver you have installed? Win 8 has a native USB 3.0 driver, if your on win 7 download the latest driver from the vendor. Then Uninstall the USB 3.0 Host driver. Reboot and install the latest driver you downloaded or If Win 8 the driver should auto install to the default.

Recently, I tried to connect something to a USB port, but they suddenly stopped working. I thought it was just the front 2 that were the problem, but then I tried to use my printer and since it's plugged in the back I thought the 2 USB ports in the back would work, but there was not connection to the printer. Now all 4 USB ports don't work. The wierd part is that when I try to plug in a USB jump drive, a light does blink on the jump drive for a split second so it seems like there's still power. I've uninstalled the USB stuff in device manager and rebooted, the computer does recognize the ports and said they were working properly, but the devices I plug in still don't work. Is there anything else that can be done about this problem? I know my jump drive and printer still work.

So one day I was using a laptop wirelessly when the internet just suddenly turned off.

A:Wireless router suddenly stopped working (Lights still working though)

what devices do you have connected the router anything else wireless
make and model of the pc

does the PC work if you connect to the router by a cable ?
if not
try connecting directly to the modem and see if that works OK

we need to see some details, which will mean you need to copy to a working PC
{run Xirrus Wi-Fi Inspector} Download and install
If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC

Direct link to the program is here http://www.xirrus.com/library/wifi_download_redirect.php
Then run and install the program
if you get an error - You need NET Framework installed for the WiFi Inspector to function.

Run the program

post a screen shot of the program running - if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information, and also post which network "Adapter Name" (1st column) is yours on the list

uninstall the new stuff and restart with the printer connected.
this should reinstall that device and it should work more than once.
Once that is stable, repeat with the dvd.

I can uninstall the USB Root Hubs, but the 3 Host Controllers will not allow me to interact at all, i.e. I when I try to update the driver, disable it or delete it then the window freezes until I stop the process.

I have updated the BIOS to the latest from the HP website and made sure that USB is enabled.

Searching the web I have tried a few driver check programs, all of which says nothing about upgrading the USB.

One thing to mention.... from the MS website it states that USB usualy uses IRQ 9 whereas my USB Controllers are on IRQ 19.

Any help gratefully received

You cannot update...USB controller drivers, those are installed by Windows. If they are damaged, updating won't necessarily overcome that.

Go to Device Manager...ignore the hubs, uninstall each controller...reboot.

hi guys, this problem has been plaguing me for a long time now. tried searching everywhere but none of the solutions seem to be working. My USB ports were working fine until one day when i uninstalled my HP printers drivers and software. It doesnt show any problem in the Device Manager(i.e no exclamation marks) but devices seem to be drawing power from the ports, only windows does not detect these devices. When i plugin any device, i don't get the sound which i usually do nor a popup from the system tray. Plz guys help me out as I;m really really stumped.
Im using Windows Xp Proffessional with SP2.

A:USB ports just stopped working !!

Read other 12 answers

It would be great if anyone has an idea what kind of problem I am dealing with here.
Two days ago, my USP ports just stopped working. I turned off my Toshiba Satellite A305-6829 in the evening, the next day I turned it back on, nothing.
I tried to connect my mouse and two different external hard drives, their light is on, so there is power, but the devices are not recognized.
In the device manager, it shows a yellow exclamation mark next to all the USB ports and under properties it says "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)".
I tried to uninstall the drivers and reinstall, it's still the same.
Is there anything else I can do? Is it likely to be a hardware problem? The laptop is only 4 months old and everything else works fine.
Thanks so much for any suggestions,

Try this fix by JohnWill

Johnwill's solution

Create a file with NOTEPAD containing the following lines and save it as FIX.REG
-------------------------- Use text after this line --------------------------------

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

-------------------------- Use text before this line --------------------------------

Double click on FIX.REG and say yes to the Merge Into Registry question.

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Disk Drives that you know are not present.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

Hello I'm new to this so I'll try my best to explain the problem. I have a wireless mouse that stopped working, the problem is when i plugged the wireless receiver in the USB port, the computer says "found new hardware" and hardware is installed and ready to use. The mouse works for a couple seconds but then after that they stopped moving, after I restarted the computer, the mouse still stands in the center on the screen, so I tried a different port the same thing happens and if I use the the USB port already the mouse won't even move for a few seconds. Its not the mouse's fault because I asked my neighbor to borrow his mouse(which is USB plug mouse) and the same thing happens just like my mouse. I tried to to see if its the USB devices' problems but I use my flash drive and it works so its not USB device's problem so I'm wondering if some one could help me with this problem.

Look in your device manager and see if any USB devices have show to be not working or not installed. In any case try deleteing the USB Controller and letting Windows reinstall it.

I recently acquired an HP Elite model H8-1050 and I reinstalled my OS from scratch (Custom Windows Ultimate). In the beginning the 2 3.0 ports on the top of the unit next to the stereo jack and mic port were working. After installing the OS, flashing my BIOS and updating all drivers they are no longer working by which I mean when I put a flash stick or other USB peripheral nothing happens. Now I'm pretty sure it's a software issue because the stereo out and microphone ports work fine and they are all a part of one piece of hardware and because they did work at some point. It's a fairly new device still long under warranty so I doubt it could have failed so quickly.

I looked in my bios but couldn't find any settings that relate to USB and in my Device Manager it shows no unknown devices. HP upper level tech support wasn't much help either and wanted me to reinstall my OS entirely or backdate my bios flash which is both crude and risky. For reference he tells me I have an IPISB-CH2 Pegatron Mobo. I used the bios flash and controller drivers directly from HP's website for my model. Any ideas? I'm wondering if there are separate 3.0 drivers I need. Google H8-1050 drivers (64bit) to see exactly what I used.

Nothing I plug into any of my usb2.0 ports will work.

I get the message 'USB Device Not Recognized - One of the usb devices attached to this computer has malfunctioned, and Windows does not recognize it. for assistence in solving this problem click this message'

Clicking this message inevitably didnt help.

This has only happened today, and I only noticed it after installing Daemon Tools v4.0 which I have now uninstalled which hasnt solved the problem. This could of course be a coincidence.

Can anyone suggest anything I can try? Let me know any information you need and I will post it.

Thanks in advance

I am new here and not sure if this post belongs here, if not please point me in the right direction.  
About five month ago I built a pretty basic computer. I have been using a pretty crappy tower since then and today upgraded. I switched out all the internals and set everything up in the new tower. After booting up into windows (8.1) anything connected to any USB port would become unresponsive. Although every minute or so the number lock light would flash signifying the keyboard was receiving power for a split second. I shut down the computer and booted into BIOS and the keyboard worked perfectly. I also checked to make sure the USB ports were enabled in one of the BIOS pages. Even after this the keyboard and mouse refused to work after entering windows.

I am using an HP DV9310us laptop with Vista Home Premium SP1 32-bit, and an AMD Turion 64 TL-52 processor. (Let me know if you need any more info to troubleshoot)

A little over a month ago, I plugged in an old optical mouse to my laptop, which I had previously used on a much older desktop.

Almost immediately, I got a popup message saying "One of your USB devices is malfunctioning". The mouse didn't work in that port, so I tried another one. It worked for a few minutes, then I got the same message again. I unplugged the mouse and decided to give up. A few minutes later I started getting the same error message over and over again multiple times in rapid succession, with nothing attached to my usb ports. I wish I had written down or copied the exact error message, but I didn't, and now it's too late to remember the exact message. At that point, I was sleepy and I decided to deal with the problem the next day.

When I woke up and tried to plug in a different mouse (which was working on said laptop previously), I discovered that NONE of my USB ports were working at all. Since then, I have tried every fix I could find on the internet, on many different forums, and nothing has worked.

Upon further inspection, I noticed that the USB ports still supply power (sort of). For instance, when I plug in my usb hard drive, it lights up but doesn't spin, and nothing is recognized by the computer. When I plug in my Windows Mobile Phone with the usb charge... Read more

A:All USB ports stopped working!

Hi, all of my USB ports stopped working. I have a 9mth old Dell Inspiron 5759 with Windows 10 and all updates. In DEVICE MANAGER, it shows all USB drivers as up to date and running correctly. Have though about uninstalling/reinstalling them but were do i get the replacement drivers or will Win10 automatically see they're not there?
If i plug in my MP3 player it is not recognized at all and won't charge/sync. DEVICE MANAGER shows it as an unsupported device and says "The drivers for this device are not installed. (Code 28). A service installation section in this INF is invalid. To find a driver for this device, click Update Driver." To my knowledge, the device does not have a specific driver and Sony does not provide one. I have never needed one previously.
If i plug in my phone I can charge but not sync. In DEVICE MANAGER, it shows as my phone like normal and says "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19).
Online, searching "Code 19" seems to apply to CD/DVD drives and mine will now not play CDs and I cannot see it in Win Media Player but I can see it in File Explorer and click on it but nothing plays. Music on my hard drive plays normally.
Any help anyone can give is greatly appreciated. Thanks.
