Hardware Drivers :: Unknown USB Device (Device Descriptor Request Failed)
Feb 8, 2014
Last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???
Does Windows 8.1 having driver WHQL problems?
I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.

(Unknown USB Device - A request for the USB device descriptor failed)
Massive problem I have encountered since buying a new laptop pre-installed with Windows 8.1
I have 3 external USB storage devices - 1x Corsair "Slider" 64GB, 1x HiTachi Touro 750GB, & 1x HiTachi 4TB external drive. ALL drives are coming up with the same error message and are not being recognized by Windows 8.1
The strange thing is, I also have another 2 PCs - one with Win7 and one with WinXP and the drives work without issue.
Why ALL of these drives do not work on this new laptop pre-installed with Windows 8.1?
Even stranger still is I have other thumb drives, a cheap Transcend 32GB (which is USB3.0) and a few cheapo (USB2.0) drives of various sizes by Strontium, Lexar and so on which work perfectly.
But the one that has me o.O is an expensive 64GB thumb drive called the Mach Extreme which also works perfectly with this laptop???
So all up 2x HiTachi drives & 1x Corsair thumb drive are not working and its driving me bonkers!
If no drives worked at all, then I would be seeking the manufacturer for maybe a faulty component. Dodgy USB ports, or maybe a motherboard problem. But having a handfull of drives, of various makes, sizes and both USB3.0 - 2.0 fully working leaves me scratching the old chrome dome as to what could be the issue
The HiTachi 4TB drive is my main storage device, I'm preety much stuffed if I can't get this drive working with this laptop. The same goes with the 750GB too. I REALLY need these 2 drives functional with this laptop.

I have a flash drive that I previously used in public computer lab (where many viruses linger) the other day to do my work. As I got home, the flash drive isn't working anymore, saying "USB Device not Recognized". I also noticed that it really took me a while to finally, safely remove it from the computer lab's PC. So I actually wonder if it actually removed my flash drive properly.
On Device Manager, it says "Unknown USB Device (Device Descriptor Request Failed)".On the Properties, the device status says "Windows has stopped this device because it has reported problems. (Code 43) -- A request for the USB device descriptor failed."
My flash drive is a Kingston Flash Drive DataTraveler (DT100) 16GB, and my PC is running on Windows 8.1.
Things I have tried:
- Shut down my PC, unplugged power and removed battery, waited for a while, booted my PC and try plugging in again.
- On Device Manager, uninstalled it and scanned for hardware changes, it still returns as "Unknown USB Device".
- On Device Manager, I clicked "Update Driver Software..." and it returns me a message saying "The best driver software for your device is already installed".
- Unfortunately, when I visited Kingston's website to check if there is driver for this specific flash drive, there isn't any... "There are no downloads or drivers available for this product".
- Used Windows 8's Troubleshooting tool. It only detected my problem, but was unable to fix it.
- I also tried plugging it to other devices that are running on Windows XP, Vista and 7, none does any better.

I have 1 pair of Razer Megalodon USB headphones, on the start up of Windows 8.1 these headphones are not detected correctly. The only proof I have of this is in the device manager displays:
Universal Serial Bus Controllers -
Unknown USB Device (Device Descriptor Request Failed).
(Please see attached screenshots)
Once the device is disconnected and reconnected device manager then displays:
Universal Serial Bus Controllers - USB Composite Device
The device then shows in "Audio inputs and outputs".

First my computer when bought came pre installed with Windows 7. As soon as Windows 8 came out I upgraded to Windows 8. My system is BIOS not UEFI. I have about 3gb ram and 500gb hdd drive 2.20 ghz processor. Windows 8 runs really smoothly. So recently 2-3 days ago I decided to dual boot Ubuntu with Windows 8. Before when I had Windows 7 I dual booted it with Windows 8. So now I thought about dual booting with Ubuntu 12.04 LTS. The Installation process was fine until I take out the installation usb with Ubuntu and whenever I try to restart it the PC would hang on the oem screen for a while which is ridiculously long.
Then when I would boot into Windows 8 and sign in I would get a notification message saying the last storage device you plugged in isn't found. I went to the device manager in Windows and it would say an unknown device has been found and even if I tried to Uninstall it would come back again. I tried searching for updates but nothing came up. I googled it and got no results. What annoys me the most is the PC hanging on the oem screen. Right now I fresh installed Windows 8 so it's the only OS running at the moment. But I want Ubuntu 12.04 LTS because of git, ssh and all the server side stuff. I have also posted the error screenshot for more info.

I just reinstalled my PC, obviously with windows 8. And I can't seem to play games, i mostly play COD4 and whenever I join a game, I get an Dirextx error, or my PC just reboots..
I don't know if it has something to do with my LPC INTERFACE controller.
LPC One:
on Intel(R) ICH8/ICH8R Family LPC Interface Controller - 2810
The drivers for this device are not installed. (Code 28)
To find a driver for this device, click Update Driver.
Games one:
directx unrecoverable error
And I used to get 'AMD Driver timed out, and succesfully rebooted" something like that.
This is my setup:
OS: Windows 8
MOBO: FOXXCONN p9657aa-8ks2h
CPU: Intel Core2Quad Q6600
RAM: 2GB ddr2
GPU: Club3D Radeon HD 6970 Coolstream Edition
HDD: dont know really, 300gb

I have a Seagate GoFlex 1 Tb USB 3.0 drive. All worked good until a week or two ago. Now the drive will not be recognized when plugged into a USB 3.0 port, the error given is "Unknown USB Device (Device Failed Enumeration).
If I plug the GoFlex drive into a a USB 2.0 port, it works. I can plug USB 2.0 devices into the USB 3.0 port and they work. I just can't plug my USB 3.0 drive into a USB 3.0 port and get it to work.
I have tried uninstalling the Unknown USB Device in Device Manager. I've also uninstalled all other instances of it failing to be recognized.
My motherboard has a VIA VL805 USB controller. I've used the drivers on Gigabyte's site and I've used VIA's drivers, no difference. I have the latest BIOS for my motherboard.
The drive does not show up in Disk Management when plugged into a USB 3.0 port. This shouldn't be a surprise since the device is unknown in the Device Manager.
I thought the problem might be with the USB 3.0 cable or the GoFlex drive's USB interface. So I bought a new USB 3.0 docking station and...same problem. The new docking station also fails enumeration. Basically what it boils down to is a USB 3.0 storage device will not be recognized in a USB 3.0 port. But they work when plugged into a USB 2.0 port.

When I try to add from my mobile device it fails to add by showing a message as shown in the next picture.

I'm not truly the best with computers, and this is a new pop up for me. I just purchased this new dell laptop in May and have had no problems with it. However, in the last few weeks I've been getting a new pop up in the right hand corner. My house hold have a wireless router that is password protected. I have McAfee Security Center updated, and shows that all my firewalls and security systems are on and active.
However, this is the message I get and I'm concerned about my networks safety:
"Unknown PC or device detected
This PC or device has connected to your network:
IP Adress xxxxxxx"
I've opened my action center to make sure everything is okay, and the only thing I find that isn't turned on is the "Network Access Protection" - which is something I haven't touched before, nor does it provide a link in which to turn it on.

The light blinks red 4-5 times and blue/green once. ive searched online to see what the problem is but i cannot do some of the fixes as the computer is at 0% battery.

I am unsure whether I should enable "Automatically get device drivers, apps, and info for new devices" when installing Windows 8 Pro?
What exactly will it do?
If I enable this, will Windows then automatically install software packages/drivers from the manufacturer, like for example the Logitech Setpoint software for their keyboards and mouse and similar software for other devices? I don't want or need that. Or will it behave like in Windows 7?
On my other PC with Windows 7 I see in Windows Update that there are a couple of optional updates, including that Logitech stuff, as well as some driver for a BenQ monitor I have and also nvidia video drivers. This kind of stuff I don't want or need installed automatically as important updates in Windows Update - so I am worried if enabling this automatic driver stuff in Windows 8 is different than Windows 7? Meaning that it will get installed secretly/automatically?
However, it's fine that Windows finds them so I can manually go and check if I want to install any of it.
The key is that the updates are optional in Windows 7, but I have seen a few people complain about Windows 8 installing stuff like video drivers and mouse drivers automatically.

I've installed Microsoft Windows 8.1 Version 6.3.9600 Build 9600 on my HP 430 Notebook PC with 1 GB RAM and Pentium CPU @ 2GHz 2 Cores.
Display drivers are not working properly (i.e., everything appears bigger and unclear), earlier I'd successfully updated the display drivers and made it work using Device Manager. making a backup of the drivers (may be in .inf format) from the installed drivers so that I don't have to update it every time I re-install it.

I'm running a custom build PC on which I clean installed a (legal) copy of Windows 8.1
My system works fine except it can not install drivers for ANYTHING non-standard. Keyboard, mouse, memory sticks, HDDs all work fine, however when I plug in my phone/tablet/camera etc via USB, it fails to install drivers and I can't use my device.
Here's what device manager looks like with my (android) phone plugged in
And when I select Update driver software, I get this error:

I recently bought a cheap USB Hub off eBay. I plugged it in and connected my devices and it always works.
However, about 75% of the time when Win 8 boots, I get about a dozen "USB connect/disconnect" sounds and a window that says "USB Device not recognized". (sometimes 3 or 4 of these windows)
I've searched for this issue but every post that I find provides a recommendation for a USB device that is not working. None of these suggestions applies because after all the boot noise, the hub and it's devices work. It just seems like Win 8 is having trouble recognizing the Hub but keeps trying and eventually succeeds.
The Hub is plugged into a USB 2 port with a scroll wheel mouse and a Dymo LabelWriter 400 connected to the hub.

No USB device seems to be getting detected on my machine when I plug in a flash drive or an external hdd I get the distinctive sound from my speakers that an USB device is plugged in but nothing is showing up in "My Computer". I went through the event logs and found that Windows is failing to load the USB device (check image in attachment logs.jpeg). Recently I installed iTunes, so I though it might be causing this problem but I uninstalled it even then the problem persists. I don't want to format my machine just because of this small problem. Is this a driver conflict ? How do I find out why windows is all of a sudden failing to load the USB devices ? I have uploaded a copy of the saved logs detailing this failure(logs.zip).

I have a strange problem: connecting a Canon Powershot G10 digital camera via USB 2.0 to my Win 8.1 laptop presents no problem (info pops up).
But: Using the same cable connected to my desktop PC, there is no reaction whatsoever. No device manager listing, no error message. The USB ports are all working perfectly with other devices (sticks, external hard drive, wireless mouse & keyboard). Moreover, until some weeks ago, the Canon camera was recognized normally.
Short of re-installing the whole USB controller

When I connect my DualShock 3 controller to my Windows 8.1 laptop it does not charge. I hear a beep, as in something was connected to the PC, then it seems to charge for a couple of seconds (lights flash on the controller) and then it stops. I am able to charge my phone and tablet so, it's just the DS3. It works fine on my Windows 7 computer, so it's not the controller.

A couple days ago, somehow, I turned on 'scanning your device' and now I get a black screen every time I plug my phone into the USB port to charge it. how to disable this 'feature'. It's really annoying because the connection is a bit worn, and it keeps connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...connecting and disconnecting...
I don't want anything to happen when I plug the phone into the USB port.

I'm running Windows 8.1 on a SDD with a second HDD along side it. Inside the Device Manager I disabled my second HDD and rebooted my system.
Windows started as normal, but a few key windows programs have stopped working:
- Task Manager
- Device Manager (basically all control panel functions)
- Powershell (Command Prompt Works, but can't be opened with administrative rights)
The main problem is that I now can't enable my second HDD. Why the HDD is needed for these programs and how I can re-enable my HDD?

Recently my "PS to PC Converter" USB device, as shown in image was not recognized by my laptop. It was working fine as of yesterday, where I was playing FIFA with my friend. Then today when I plug it in, it says USB device not recognized even though I can still on the analog but the controller is not detected by the game. Other games that I use to play with controllers are also not detecting the device. I kept reinstalling the driver but still the same message. Restarting computer, turning it off for a few minutes did not solve my problem too. I'm pretty sure my USB ports are fine as my mouse, keyboard and hard drives are working in all of the USB ports.
EDIT: I check the Device Manager and found a yellow exclamation mark on Other Devices named "Unknown device", I check the properties and says Code 43 on the status. I Enable/Disable it, still the same message.
