Usb ports giving power but not detecting devices at all.

Q: Usb ports giving power but not detecting devices at all.

I have dell inspiron 5520 and previously windows 7 was installed on it and now I have clean installed windows 10, after installation i noticed that usb ports are no longer detecting devices. In the device manager i can see exclamation mark on USB xHCI compliant host controller with error code 10. It must be some driver problem. I tried every solution on the internet related to this problem but all in vain. Please help its really frustrating and disappointing.
I have tried following solutions so far:

uninstall driver and restart
installed windows updates
downloaded drivers from vendor's site
updated bios

A friend of mine has same laptop with windows 10 and his ports are working.

Preferred Solution: Usb ports giving power but not detecting devices at all.

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: Usb ports giving power but not detecting devices at all.

Open device manager and uninstall or remove the host controller then shutdown and reboot the computer. Windows should recognize the controller and install drivers.

A little background info:
I had a friend of mine build this PC for me a few days ago, its custom. 
This is the motherboard I bought (new): Z-97A
I did a lot of upgrades so we had to do a custom install, I chose the default location to the same drive as my original W7 OS was on.
I installed all the drivers that came with the motherboard and all windows updates.
Even if they are not recognized the devices still get power (like my phone will charge but the PC doesnt know what it is or even see it as unknown)
While gaming 2 nights ago one of my presumed dead USB ports that didnt read my Sennheiser headsets randomly began to read it & automatically installed drivers for it after I was initially unable to get it to detect before. So it just kinda came "alive" on its own you could say
I've attached screenshots of my devices and printers and device manager

4 weird things about the devices and printers list:
You will see in devices and printers it says I have 3 Keyboards, I only have the one on the far left.
I Only have 1 Playstation controller
When my Sennheisers were detected I immediately installed the drivers for them from their website but now it shows up as "Unspecified". Before my reinstall of windows I am pretty sure it listed in the devices category with a picture of the headset.

A:Some USB ports not detecting devices + Duplicate devices showing

FWIW:  Duplicate devices may appear...if one device is used to install...and a different one is used later, IME.
 
The ximple way to remove any apparent dupes...is to delete them via Device Manager (including the use currently installed)...then reboot and reinstall the drivers if they are not automatically reinstalled by Windows.
 
Device Manager typically reflects such items on a given system, see Remove Unused Drivers and Devices - http://www.windowsnetworking.com/kbase/WindowsTips/WindowsXP/UserTips/TroubleShooting/RemoveUnusedDriversandDevices.html .

Hi all, it's friday the 13th and on cue i have another weird one i have a PC that does not detect any USB device connected to it though i know power runs through since it can charge my cell phone. here is what i have so far: 1. WinXP home SP2, P4 2.63Ghz, Gigabyte 81845GVM-RZ, 256 DDR400. 2. have uninstalled all usb root hubs and rebooted 3. 2 ports at the front of the case and 2 at the rear, plus (here's the punchline) 2 ports from a PCI add on card. NONE of them work. 4. USB controller is enabled in BIOS. 5. while my cell phone charges blissfully, the power tab of all root hub properties still shows 0mA 6. i've tried clearing CMOS 7. i've done a repair (NOT full/format) installation of the OS 8. to try and isolate the issue, i've tried booting from miniPE (a WinPE variation) while a USB flash drive was plugged in, it's worked for me before, nogo here either. what have i missed? not sure about changes made to the system prior to this since it's someone elses and they can't say for sure either. i'd settle for it being a mobo issue and recommend they trash it, but an add on card too? please help guys, you've saved my posterior before, so i'm counting on you. thanks.

I'm running windows 7...
I have 4 usb ports on the back, two on the front
All usb ports appear to be giving power, i can charge things (except ipod), but no devices get recognized in windows
So yesterday i plugged my camera into my computer and it cause my mouse to turn off. After which i plug my mouse into a different usb slot which seem to work. After a while i notice though that my mouse would lag and cause my computer to not response for a few seconds every once in a while... The next day when i came to my pc i notice my keyboard was turned off... I tried to move it to different ports and in every port i would get "Device not Recognized or malfunctioning..." No usb device gets recognized anymore, except my razor mouse, for some reason this gets identified.

Right now i have no keyboard and i can't go into my bios or re-install my OS... I tried putting BOTH my keyboard and mouse into usb-ps/2 converters but when i plug them into the ps2 ports nothing happens... no windows device sounds, nothing happens...

I tried uninstalling my usb controllers from device manager, as well as manual install my dell keyboard drivers (NEITHER DID ANYTHING)

I'm pretty much lost for ideas here...

PS/2 ports are, I think, not plug and play. Try shutting down the system and then boot with the keyboard/mouse plugged into the PS/2.

I have an Acer Aspire M5 481PT-6644 running Windows 8.1. While using a wireless mouse, the mouse became disconnected from my computer (not physically disconnected, but an error message popped up saying the device was not recognized). I pulled out the USB wireless transmitter, plugged it back in, and it re-connected with my computer. Shortly thereafter the mouse became disconnected again (same thing as before with an error message) and now no USB device will connect to my computer. I will get power from the USB port, but it will never recognize devices and nothing shows up when I scan for new devices.
My computer has 2 usb 3.0 ports and neither port works. I made sure to try multiple devices and check that these were working on other computers.
I first tried deleting all of the USB drivers (every driver listed under the "Universal Serial Bus Controller" section in the device manager) and then restarting the computer, but the problem remained.

I tried using a system restore point, but the USB ports still weren't recognizing devices even after the restore (though I am not 100% the restore point was far enough back since I tried a lot of different things before doing the restore).

Hello! I have a desktop computer and several days ago my old 500W power supply burnt out (from overheating I suppose) while the computer was on. I replaced it with a new one, 750W, but when I turned it on everything was working properly except for the fact that no USB devices were recognized. I have 2 USB 2.0 front ports and four rear ones. Power reaches all of them, since LEDs on devices connected light up, but OS does not indicate any devices being connected. I tried switching off the PC from the mains, pressing and holding the power button, even removed the battery on the motherboard and reset the BIOS settings. Nothing changed. I have a dual-boot PC with Windows 7 and Gentoo Linux. Neither of the two operating systems give any errors concerning the USB ports and neither recognizes anything plugged in. My PC is:
MB: ASUS P5B
CPU: Intel Core 2 Duo @ 2.33 GHz
HDD: Samsung HD403LJ ATA 400 GB
I don't have a USB keyboard nor a mouse to try and see if they work during BIOS boot. Does anyone have any suggestions?

I have a Satellite L305D-S5928 running Vista 32-bit.
For over a year now I've had problems with my USB ports. All 3 of them.
The ports deliver power to devices, but no devices are recognized by my computer, nor are the device's drivers able to install.
All devices WORK on other computers.
I'd list the solutions I've tried, but it would literally take me ages to remember/write them all down. Mainly because, I've tried every possible solution I've found, and I'm not exaggerating.
At this point, my only hope is that someone on here can help me.

I know this is a vague start, but I would really like to use a mouse, use Auto-Play for my iPhone, or even use a USB flash drive.

A couple extra things;
-I have been in to regedit, and device manager none of the solutions I found regarding changes/deleting/enabling/etc. worked.
-Tried finding new drivers, wasn't successful. (But also had trouble finding necessary drivers, Toshiba site isn't super helpful.)
-I haven't taken my laptop apart, but I don't feel like the USB ports are damaged.

Fingers crossed that someone here has a new idea, or a solution. Thank you to all who try to help.

My HP Pavilion G6 has been into geek squad twice now, and each time it has come home and worked seemingly okay for about a week, and I have problems with it again.
In the beginning of it all, whatever has infected my computer corrupted 2 USB drives. I ended up putting the files back on the computer, as it had some important school documents. (If it helps, the USB drives were lexars.) I have also been experiencing problems with a portable mouse, (Logitech), where it will simply not work. When I try and shut it down in the start menu, It will fail, and give me a blue screen with "USB_BUGCODE_DRIVER" scrawled near the top in all caps. It will also, when on, have lines move up and down it. Like I said before, geek squad has looked at this twice, and hasn't solved the problem to a full extent.
Since it happened during the time that it quit working for the last time I downloaded "Monaco" on the steam store on a whim because it looked fun, and it was free. When I gave it access to my hard drive and launched it, it froze up and I had to use Ctrl+Alt+Delete to get the screen to go back to being normal. This is when the mouse quit working, and no buttons on the keyboard worked. I shut it off using the power button, and when I started it the mouse didn't work. This confused me, because I thought the Steam store was secure.
I have also tried to reset it to the day before it went foobar using the system reset, but it gives me the same USB_BUGCODE blue screen... Read more

Your drivers are corrupt. You can uninstall them and let windows reinstall them. This may fix the problem . But if the usb ports are bad. You will get the same problem back. You can also try a restore point to when the computer or laptop usb ports were working fine. I hope this helps.

A:detecting devices

Have a look in Device Manager. If you see one or more yellow question-marks in the device list it means you need to install the drivers for the devices which currently don't work. The drivers can be downloaded from your PC or laptop maker's website if they support Windows 7 on your particular model.

Hi,

Sorry, but it sounds as though you have a physical hardware problem. Without opening up the computer and doing advanced and expensive repairs, there is no way of fixing this. You will just have to live with 1 USB port. You could however buy yourself small USB splitter so you can have more than 1 USB device plugged in at once.

Sorry again,

Hi,

I've recently made a SP3 update on my Windows XP Home. Initially I kept on getting blue screen with this error. I was unable to load Windows or Safe Mode.

STOP: 0X0000007E (0XC0000001D, 0XF78DE8EA, 0XF78DE7F4, 0XF78DE4F0)

After reading some forums, I've unplugged all my USB devices as some people suggest that it might be the problems with drivers.

After unplugging all USB devices - printer, external HDD and mouse, Windows loaded without problem but I got a new error after Windows finishes loading.

BCCode : 1000007e BCP1 : C0000005 BCP2 : BA5038F0 BCP3 : BA5037F0
BCP4 : BA5034EC OSVer : 5_1_2600 SP : 3_0 Product : 768_1

I suspect this error has to do with drivers.

At the same time, if I try to plug in any of my USB devices, i.e. mouse, printer or external HDD, the blue screen will reappear immediately. They used to work perfectly when I was on SP2 until last night.

FYI, I'm using Dell INSPIRON 640m laptop with Windows XP Home SP2 until the moment I install the SP3 update.

Hope I can get some help or pointers here. Not impressed with SP3 update definitely!

Thank you very much.

Hello everyone Merry Christmas.

As a gift for a buddy of mine i've promised to fix up an old computer in an effort to aid with his career as an oil painter (access to Fineartamerica, research, etc.).

But at any rate; I've done a bit of swapping around of hard disk drives and cd drives and whatnot and have decided on a very basic config. using a single hard drive in the Master slot and a single cd drive in the slave.

The problem im seeing is that the Bios is not detecting either of the drives, or perhaps very briefly then disapppearing.

At first i thought it may have been the cmos battery, because the drives would appear at first and then disappear immediately, but i've purchased a new cmos battery and its still doin the same thing.

For a while i thought i may have had the wrong jumper settings because the hd drive didnt label them, but i checked a diagram online of an identical drive and its set at the master slot; and the cd drive at the slave.

I've tested it with several IDE cables in multiple channels and it still gives me the same message when turned on 'Reboot and select proper boot device or insert boot media in selected boot device and press a key'.

also, the disk drive opens and functions properly when IDE cable is not connected, but when it is connected it doesn't appear to be getting any juice.

any thoughts?

thanks-chris

Hi,

I have an old Athlon xp 2800 running XP sp2. After expanding its memory I had some "blue screen" events... I did some "house keeping" and apparently everything is fine again.

However, Windows seems not to recognize any devices attached to the computer. This applies to printer, sound, USB ports and even the network card (despite I could make it work after the house keeping).

When I open the Device Manager, it shows a blank page, as if there were no hw devices on the computer. Also, I tried to force a hw detection but it simply does not work.

I ran chkdsk /f several times and nothing was found...

I am afraid some windows files got corrupted.

Time for a re-install, and look at your BIOS setups closely... you likely have some problems that can be corrected with changes as you boot to <F2> or <F10>
Start with Default, then go through each setting on the list. There are specific settings for IDE/EIDE... and they are not always obvious changes by the way they are worded...

Hello, I've been experiencing a string of bad luck with my Asus G75VW laptop.

Recently my 1TB harddrive showed signs of dying, so I pulled a 70gig harddrive out of an old laptop and replaced it till I got a new drive. A few days later the 70gig puckered out as well, I just wiped it and reinstalled windows and it worked for a day or two and then it failed again. I decided to pull another harddrive out of another laptop I had and after a few hours of it working great, my computer began to start freezing and then blue screened. After it crashed, I powered back up and now I can't see any options for bootable devices; no harddrives, no usb, not even my DVD drive. It does detect that the harddrive is there in the Sata Configuration. Also, the boot splash no longer appears when powering up if that could be a possible clue to my problem.

TL;DR After having a lot of harddrive issues, computer blue screens and now has no boot options.

I have absolutely no idea what I should check now, much love to anyone who can help me out.

A:Issues Detecting Bootable Devices

Hello and welcome Matt mate that is an awful lot of hard drive crashes and it makes me wonder if there is something else going wrong in that machine.
I would suggest if you can in safe mode run these

http://www.sevenforums.com/tutorials/433-disk-check.html < use the /f and /r options in Option 2 ifnecessary
The ultimate option would be a clean reinstall and it is easy using this
Clean Reinstall - Factory OEM Windows 7 you just need the activation code from the sticker on the machine and don't do as some do and go for a version of Windows above what was originally installed it only ends in endless grief. See pic

I have just reinstalled the OS (Win 2k) on my laptop and all went well, all drivers found, SP2 installed etc. etc.

However when inserting any PCMCIA device it is not detected at all by windows. A look in the device manager says that the two CARD bus controllers (O2Micro OZ6832......) are detected and working.

Its a VIA Apollo MPV4 chipset and a Phoenix BIOS (which i've tried reseting to factory defaults etc. etc.)

Any help or pointers would be greatly appreciated.

I'm about to explode with frustration!

Problems started when USB ports seemed to spontaneously stop working. Then Device Manager window is empty. Nothing shown at all. Also My Computer takes ages to load and system often seems to hang

Have run every spyware and virus scan possible. Followed instructions on Annoyances forum but still no joy. PnUP is switched on.

3.4GHz P4

750GB in 1x 200GB and 1x 500GB

A:Device Manager empty. USB ports not detecting

I have a partial resolution to my problem!

Thanks to everyone who offered help.

First option was check that PuNP was started - OK. Later I discovered that Universal PuNP must NOT be started!

Second option was Aproposfix which I assume is to get rid of some specific spyware/adware/malware.

Third was I tried editing some permissions in the registry but I didn't really understand what I was doing.

Fourth was I ran sfc/scannow - whatever that is!

Also system was hanging on startups and shutdowns, sometimes needing the big switch to get out of it. Now you can click on IE or My Computer or Control Panel and it takes ages for them to load. Usually I find myself with about five instances of each all loading at once.

Frequently web links won't work. The only thing I can do is avoid a left click - use right clicks to save shortcut and then paste it into address bar. I have tpo switch back and forth betwen web browsers using teh Task Manager. OIften the Task Manager itself freezes with the button still "pressed down".

I've also been using my SpeedUpMyPC utility which allows you to give CPU priority to a particular window. A combination of this, Task Manager and a hell of a lot of patience just about keeps me going

Oh, and I updated all my chipset drivers along the way.

MY DEVICE MANAGER WINDOW IS NOW FULLY POPULATED!!!!!

Oh joy! The printer is working too. The solution? It was to do with permissions. I had to spend a lot more time and give a lot more ... Read more

I just connected and disconnected my android device to the usb on my pc few times.
Then for no reason i heared some times the sound of detecting the device on/off automatic i didn't do anything but i could keep using the device on the pc.

And now again not sure what happened but now when i connect my device to the usb device it dosen't detect i at all and also other devices. No sound of detection nothing.

What i tried so far ?

1. Disabled/Enabled all usb controllers in Device Manager > Universial Serial Bus Controllers.

2. Restarted pc didn't work so now i tried to shut down the pc also didn't solve it.

3. I found window hotfix should be also for windows 8 but when i tried to run it i got message error it's not for my window. I have windows 8.1 pro. This is the hotfix i tried: https://support.microsoft.com/en-us/kb/2830154 not working.

Now i see another thing in the Device Manager i see yellow on: Unkown usb device, I tried to disable and uninstall it if i uninstall it it's gone. Tried to connect the device to the pc again nothing. Disable didnt work updating drive not working.
What else could make this problem ? I had the same problem few days ago so i shut down the pc and it was working again.
But now nothing help.

A:Windows stopped detecting usb devices how to solve it ?

Did you try deleting or uninstalling all the usb devices and rebooting? It is an old support trick to get Windows to reinstall the same driver. It seems to work as often as not.

If it does not work after that, at least for a short time, it may be a hardware issue.

Hello everyone...

I have a brand new Acer Predator AG3620. It has an Intel I7, 12 GB of RAM and an NVIDIA GeForce GT 630 2GB video card. It shipped with a 2 TB hard drive and Windows 8 which worked fine.

I installed a Mushkin Chrone 240GB SSD drive and wanted to install a clean copy of Windows 8 on there to remove all the Acer bloatware. This is where my life ended... After an unfortunate series of incidents, I am finally at the point where the BIOS (or whatever they call it these days) recognizes and boots from the drive. However, the Windows 8 installation will not complete.

It gets to "Detecting Devices" and after it gets to 69%, 72% or 79% (it changes all the time), the system reboots and I get an error message, "The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed. To install Windows, click "Ok" to restart the computer, and then restart the installation." After searching tirelessly for a solution, I realized that Acer had a BIOS update which I installed and I am STILL having the same problem.

I suspect there is some type of hardware compatabilty issue but I am not aware of any logfile that can help guide me. I have done this installation about 20 times in the last few days and it is absolutely maddening. It just WILL NOT work! I have read every post I could find and tinkered with every setting in the BIOS, port on the motherboard and SATA cable I have. I have gone from AC... Read more

A:Clean install on SSD keeps failing at Detecting Devices..

Your suspicions are correct. I have had the same problem on several different models, since the earlier public previews. There have been three or four solutions offered, even on this site, none of which have worked. In particular are older HP models, especially the Envy15, but some Acers are also experiencing the problem.
Bu you could be lucky. Do you not have any restore disks which you could experiment with? Final solution for you is, of course, to return the old HD to the machine and hope all is well.
Popular theory is that it is the graphics card. This idea doesn't sit well with me, as when I have encountered that particular problem with other machines, it merely reverts to the Default VGA screen, which, of course, it has been using right through the install process.

My Verbatim 1TB USB External Hard Drive was hanging my PC at boot message "Auto Detecting USB Mass Storage Devices... Device #01. An old thread found on this forum had a similar problem with a WD 1TB My Book. The solution found then was changing the BIOS setting to DISABLE Legacy USB support. When I checked my settings I found my Legacy USB support was set to AUTO. Following the prior threads success I changed the setting to DISABLE and the problem was solved. Apparently when faced with the choice of Enable Disable or Auto, the Auto setting doesn't always choose the appropriate action. Thanks guys and gals for a great forum site.

I had just reinstalled Windows 7 professional on my laptop (dell latitude E6440) because of some issues. Well the reinstall went thru perfectly and had no problems. But now it won't connect to the Internet and won't let me make a connection. A box keeps coming up saying "not connected-no connections are available". Then when I click on the Internet and try to set up a new connection it comes up saying "Windows did not detect any networking hardware". This kinda sucks so I was wondering if anyone could help me out and figure out how to fix this.

Suddenly WM said that I needed to connect my devices before I could burn a CD. The thing is my devices are internal. It was working and then the next day it's not. Nothing has changed from what I know, no viruses have been found, no spyware, etc. I've tried uninstalling and reinstalling and microsoft.com has absolutely no help regarding this issue. Any ideas what might be the problem or should I just say the heck with it and try to find a freeware program that'll let me burn CD's to play in my car.

Just a note that I didn't include before is that I know my drive is working because I tested it with another CD.

I have 2 external displays connected through a 40A1 pro dock for VGA and Display port and 1 HDMI display connected using USB-C external adaptor. The three displays worked perfectly until yesterday for the last year. I had a power cut and now only the VGA connected display works. Both digital outputs will not recognise the externally connected display.During the power cut both displays remained powered, even though only the laptop had battery power, which I thought was quite strange. Does the USB-C adaptor provide power through the HDMI port to power the display, I thought this was impossible.However after the power came back both displays connected through display port and HDMI no longer work. I would like to know if this has been seen before and how to fix. I have updated all drivers and completed the diagnostics tests, everything seems fine and up to date.I am guessing that there is some fault on the motherboard due to excess power fed to the external displays during the power event and now the laptop needs a new part. However, I would love for this to just be a software fix.

As the title suggests, my on board sounds, seem to have failed, every time I boot, I get a Windows Troubleshooter telling me that the audio devices and services are not enabled or started, the troubleshooter fails without any errors to report (will grab a screen of this when I can)

Here is a screenshot of my windows systray showing that windows says there are no audio devices along with my playback devices window, showing speakers connected (no volume marker next to it if you notice)

You can find my full system specs listed in my profile, don't really wanna type em out again.

I went into device manager and uninstalled all my sound and video drivers and re-installed all fresh from AMD/Realtek (AMD Omega Catalyst Version 14.12 and Realtek HD Audio Codec V2.75)

EDIT: ADDED Windows Troubleshooter Screens






Any assistance would be excellent.

Sry for large sized post, spoiler tags not working?

A:Realtek/Windows Sound not working but detecting devices.

What I recall, this is a Windows problem and not a problem with the sound drivers.

Run the SFC /scannow three times and see if that helps. It may take a reinstall.
