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.

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.

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

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

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.

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.

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.

My computer is fully updated and I have no other idea's what to do.

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

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.

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.

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 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.

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.

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.

My computer crashed after doing a backup and the keyboard stopped working so I decided to remove all USBs and reinsert them then all my other USBs stopped working how do I fix this ?

And I get error 28 for all my USB drivers

A:USB ports stopped working

Sometimes this is a BIOS issue.
Reboot your computer and hit the "Delete" button, during "post".
It should be a black screen with white alpha numerics. At the bottom of the screen it may tell you to hit a different key, like F2.
In the BIOS,check your usb setting, in case it has gone haywire.

Also update the info in the "My System Specs". More information makes it easier to trouble shoot.

This morning ALL of my USB ports stopped working. If I plug something into them I get an error message saying "One of the USB devices attached to this computer has fmalfunctioned, and Windows does not recognize it." I have gone into device manager and now exclaimation points or anything. When nothing is plugged in the Root hubs show working correctly. When I plug something in and check it I see Unknown Device- then click properties and get "No drivers are installed for this device"

Why would my drivers disappear. I have tried my wireless mouse, my printer and my iPod. nothings works. I did a system restore, that didn't help.

Hope someone can help!

My computer is a laptop- Acer Aspire 9300 Using Windows XP
 

A:USB ports have stopped working

Well, for now the problem is solved- I shut the computer down, UNPLUGGED it, waited about 10 seconds then plugged it back in and rebooted! Works perfectly now!!

Hope this helps someone else!! I just spend 4 hours trying to figure it out!!

I plugged an old USB TV tuner stick into my new laprtop to see if the TV tuner was still working. There was no response from a previously working USB port in the laptop so I took it out and put it into the neighbouring port. Now both ports do not respond to anything.Are there fuses built into laptop USB ports that could have blown? When I go to Device manager and do the usual diagnostics and try to uninstall the bus controllers, the uninstall `in progress` window pops up, but then nothing happens.I have to ctrl/Alt Del to get my laptop back.Does uninstalling bust controllers take a long time??

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. 
Russell

I was off work for a few days, returned and hooked up my laptop and now it will not recognize my printer when plugged into the usb port.  I tried other devices and it won't recognize any except my wireless mouse.  I have searched and it appears it could be a usb 3.0 port not recognizing a 2.0 connection...but that doesn't explain why it has been working all of this year until now.  I also notice there is only one USB Root Hub where I have 3 ports.  Do you need a root hub for each port?  The root hub is xHCI. Would appreciate any assistance.

I regularly use USB flash drives. Today, they ALL stopped working on ALL ports. They are from Kingston and Cruzer, and I have two USB 2.0 ports and one USB 3.0 port. When I plug in a flash drive, the drive letter I had assigned to it appears under This PC as a removable device, but if I click on the drive letter, I get a message, "Please insert a disk into [driveLetter]:." Also, there is no option to safely remove the drive; it's as if the drive isn't there at all! In device manager, in both Root USB Hubs and in the Generic USB Hub, I unclicked the checkboxes to have the computer turn off the device to save power. I restarted the PC, but that did not help. Could the problem be HP 3D Drive Guard? If so,is there a later version than March 2016? I reinstalled that one, but it did not help either. Has anyone seen this issue before? Thank you.

Hi,When you go into device manager under universal serial bus do you see your devices listed?-Try uninstalling drivers for pen drives and then reboot computer If you go into disk manager (right-click on start > disk manager) do you see your devices?-Try assigning new letter to drive Let me know,David

Hey guys,

Earlier today my computer just stopped recognising my network adapter. Luckily, I've got a built-in one but it isn't any good because I only get about 25% of the actual speed I'm meant to. I've tried the following to fix it:
Restarting
Unplugging the power cable for 5 mins
Reinstalling it with device manager
Using the disc
Using a different USB port
Replacing the adapter

My computer is the Packard Bell iXtreme M5850. Can anyone help me try to fix this?

I have a AMD Proc and the USB ports all stopped working, or so it would seem. My USB mouse still makes the connect and disconnect sound and works fine. My Ipod, Dig. Cam and Printer do not work now. Inside the Chipset menu in the bios I have ALL 8 USB ports working and I still have nothing, I checked and windows says they're all working in the device manager too, am I missing something, like a driver or something that is not talking properly to the pc or windows? The other USB ports, when I connect something (Like my Ipod) make an internal sound and my ipod will CHARGE but not connect to Itunes, nor will anything other than my mouse for some reason.....any ideaS?

Hi,

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

Hi,
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,
Luna
 

A:HELP!!! USB ports stopped working!

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 --------------------------------
REGEDIT4

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

"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"
-------------------------- 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.

On my Hewlett-Packard 110-412na machine running Windows 8.1, the USB ports stopped working a couple of times recently

Since USB is the only interface between keyboard and rodent, and I waited 20 minutes or so, I had to switch the machine off and back on again.

I looked in Device Manager where everything looked ok (no yellow flags). The properties of all the devices stated that they are all working properly.

On the second occasion I was writing in Notebook, which doesn't have automatic saving, and lost a lot of work.

What might have been the cause of the USB shutting down?

A:USB ports stopped working.

Bad or missing driver. You can use Speccy from piriform.com to see what it shows.

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.

My front and rear USB 3 ports stopped working. The rear USB 2 ports still work. When I plug an external HDD into the front USB 3 ports it powers up the drive, but it isn't recognized in Windows Explorer. My USB card reader doesn't light up. Device Manager doesn't show any USB 3 devices, and nothing is showing a yellow x in Device Manager.

Any ideas? The last time I used the front ports was a few weeks ago at most. There have been Windows 10 updates since then, but I don't know specifically when they stopped working.

Hi

I am running Windows XP SP3 on a HP Compaq NX6325.

A month ago I got all 3 of my USB ports stopped working. Device Manager shows each USB Host Controller and the corresponding USB Root Hub as working correctly.

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

A:3 x USB Ports Stopped working

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.
