Venue 11 Pro slim keyboard "Unknown USB Device (Device Descriptor Request Failed)" [Code 43]

Q: Venue 11 Pro slim keyboard "Unknown USB Device (Device Descriptor Request Failed)" [Code 43]

I'm experiencing slim keyboard not being recognized in the Windows 8.1
The keyboard was working fine until just one day it just stopped working.
I tried factory reset literally 8 times along with most recent BIOS update and dell's recommended update software. + power setting --> disabling power saving on USB
It still come up as unrecognized each time even with fresh reinstall.
I was wondering if this is a hardware issue or just software bug from factory reset.
I don't think there is a available driver for this kind of problem is there?

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.)

I upgraded to Windows 10 a while back. Every time I open the computer I get a pop-up notification telling me the USB device is unrecognized. I have no USB devices in any of my 3 USB ports.
I sent my computer in twice. No help. They just uninstalled everything and reinstalled everything and told me it should be fixed. It is not. I then went about updating every driver in my Device Manager. I uninstalled the Unknown USB Device and then updated
other drivers. Certain drivers (such as PCI Express Root Port #3 - 9C14) when updating would also reinstall the Unknown USB Device, which I would then uninstall and keep working down the list. At the end of updating EVERYTHING I scanned for hardware changes
and "found" the Unknown USB Device. 
From what I can tell, and I know very little about this stuff, my computer can't name one of my USB ports. Since it can't figure out what it's called it can't download the proper driver for it. Since it can't download the proper driver it can't work properly.
The practical result from this is that one of my three USB ports does nothing when I put in any USB item (connect my android phone, thumb drive, presentation clicker, etc).
I've looked on tons of forums. My current thought is that if I can tell my computer what the deice is or download the right driver and tell my computer to use that driver for this device it should solve my issue. But I don't know how to know what the name
of the USB port should be (I imagine it woul... Read more

I was just working happily when my Microsoft Bluetooth Mouse just suddenly stopped working.
The Bluetooth settings page says "Bluetooth is turned off" and there are no options on the settings page or the system tray to turn Bluetooth on.
The Device Manager now has "Unknown USB device - device descriptor request failed" where it did not before.
Other devices all seem to be working fine - USB devices plugged in are being recognized and work properly. Only BT seems to be broken.
I've tried:
uninstalling the device and rebooting
installing the latest updated chipset drivers from the dell website
windows updates
pretty much all of the advice here: http ://troubleshooter.xyz/wiki/fix-usb-device-not-recognized-device-descriptor-request-failed

Any other ideas?
Thanks

A:XPS 15 9550 Bluetooth stopped working (Unknown USB device - device descriptor request failed)

So in desperation I just went into BIOS settings to see if there are any BT settings that may have become disabled. I didn't see any, and I didn't change any other settings.
After rebooting, BT and my mouse is now working again.
Something seems to be really flaky here, but hopefully this will help others with the same issue.

Fresh install of Windows 10 and the last driver I need to sort out is the above.

I believe it is my powered USB 3 hub to which I plug in my keyboard and mouse. Technically it is working but I don't like seeing yellow triangles on devices.

So are there any fixes?

A:Unknown USB Device (device descriptor request failed)

If it's a generic USB 2.0 Powered Hub then technically there's should be no drivers needed by Windows, if it's a USB 3.0 Hub then I'm unsure (since I don't own any USB 3.0 Hubs).

Might be a Windows bug, basically Windows can't find the description information to display the Hub's name in the Device Manager example: Generic USB Hub, Root Hub Device, etc....

I'm pretty sure everything is working as should, you're good minus the minor annoyance if all device connected through the USB Hub is recognized by Windows; if you right click Properties on the yellow triangle it probably says "The Device is working properly".

I know that a similar question has been asked before but, not with the 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???
My question is; has anyone heard of Windows 8.1 having driver WHQL problems?? Very.

Any/all ideas, appreciated.

ps, 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.

A:Unknown USB Device (Device Descriptor Request Failed)

Is there only one USB port on the right hand side? Sometimes manufacturers connect internal devices via an unused USB port internally. USB ports are usually in groups of two, seeing only one port is usually a sign that the wiring has been redirected internally to something else like a Bluetooth adapter or wifi adapter. It may even be a card reader or touchpad. Is anything like that not working? If it is start looking for a driver for it.

Hello, ok so after recently doing a clean install of windows 10(please don't get me started on that mess). my system has been plagued by random usb drops. it's where everything connected via USB suddenly disconnects then reconnects out of the blue. well I was using a Rosewill Transenclosure RX200R-APU-25B USB 3.0 dual 2.5 hard drive enclosure and transferring files from one drive to another (connected via USB) when one of these drops occurred. Now whenever I plug in my hard drive enclosure in a windows warning pops up and says "the USB drive that was just connected Malfunctioned and could not be installed" and in system manager it says "Unknown USB device (device descriptor request failed)". I know it's not the hard drives because I can remove them and use another connection and they work fine, all files intact. It's just now my hard drive enclosure won't recognize. This also happened to a "Loot crate exclusive Game of Thrones stark sigil 4GB USB stick I plugged in and turned into a windows 10 install drive.

I have two issues, which I think are related. In the Device Manager, it shows under USB Controllers "Unknown device". "Windows has stopped this device because it has reported problems. (Code 43)"

I tried updating the driver, but the driver was correct.

I tried disabling the device.

I uninstalled the device. Windows reinstalled it at next boot, but the problem reappeared.

There is no Imaging Devices in the Device Manager.

At the same time, my webcam failed to open. Message "Webcamera initialization failed."

I downloaded the correct webcam program from Toshiba, installed it, but same result.

This all started when I uninstalled and reinstalled Skype. I have tried uninstalling it again, but still no webcam.

The webcam is enabled in the BIOS.

I really do not want to reinstall Windows.

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.

- 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".

A:USB not recognized (Device Descriptor Request Failed)

if you have tried on other systems using different OS then the error is normally because of issues with the item not the PC , it might be 'confused' or have corrupted data or be faulty.

If you have the data still stored elsewhere...then you may be able to reset the flash drive and see if it recognises it then.

I'm not sure if there is a reset switch anywhere on that stick.

Hi all,

(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.

I've spent the last 4 days scouring the net looking for answers, and thus I am here hoping someone can shed some light as to 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

A:A request for the USB device descriptor failed. (error43)

You can mark this thread as SOLVED!

Okay here's the fix that worked for me, maybe it will work for you.

I've always updated drivers, WinXP, Win7 and so on, the same way - download the driver, go into device manager and select browse, then point windows to the downloaded driver to update the necessary files. Its always worked that way for me for as long as I can remember.

Not so it appears with windows 8 - for some strang reason.

For me I had to update to the latest Intel Chipset Drivers, but instead of the tried and trusted methos above, you simply hit the setup.exe and let windows 8 do its thing. Believe it or not, but this fixed the issue.

Yes I had already updatd to the latest Intel Chipset Drivers using the device manager method, and yes windows "did" update ...someting??? But the USB devices were still showing the Unknown USB Device error. But using the setup.exe fixed the everything and all my USB devices are now working perfectly with Windows 8.

How, why, who knows, but I hope this works for others with the same problem.

Mods, if you feel that this thread is more of a "Windows" issue, please feel free to move this thread.

Here last year I did my second build because I was having "boot" issues. Wasn't certain what exactly the problem was at the time. But something some how screwed up the boot sequence in my system, and where everything was pretty much "outdated." I just went ahead and did another build.

Though, since then I've been pondering around with the thought of using a SATA to IDE adapter so that I can retrieve what ever salvageable data I can from one of the two HDD's that was in my last build. So I finally broke down and ordered a couple different one's earlier this week.

Unfortunately, I've been running in to some problem(s) when I try to launch with the IDE in place.

Upon initial launching, the boot sequence seem to take some time longer than it normally does with out the IDE HDD in place. Though after a 15-20sec lapse I'll get an error screen displaying an windows error code of "0xc000000e" with a prompt message below stating "The boot selection failed because a required device is inaccessible"

I searched all over online to see what that error code represents, only to get "pages after pages" of sites with each site telling me something different.

I have no intentions of using this as a third HDD in my system. I just want to retrieve select data from it.

Hello Ladies & Gents.

I would like to ask for your assistance on this slightly annoying problem.

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"

Cheers,

A:Razer Megalodon - (Device Descriptor Request Failed)

Razer is well known for BSOD drivers and problems, otherwise. (And taking very old drivers, changing nothing at all, giving it a new date and then claiming "Compatible!" with new OS.)

Perhaps give a shot with uninstalling their software, rebooting, the re-installing.

Make sure using the latest.

When all is said and done, you might just have to live with it.

Can't hurt to make sure chipset drivers are up to date. If Intel chipset, search their driver site for "Inf"

Hi, I'm trying to reinstall my sister's scanner driver because XP has decided that it's not there any more. This happens occasionally and usually reinstalling the driver fixes it (I think that's what I did last time), but this time i just can't get it to work.

If i unplug the USB cable then plug it in again, it comes up with a message saying that the device has malfunctioned and it doesn't recognize it. I have the driver CD but windows always manages to install it as "Unknown device" before i can tell it to search the CD. I've tried telling it to reinstall the driver from the CD but it says that there are "no better matches for this device". I've also tried uninstalling the program form the CD and reinstalling it then restarting the pc but that didn't help either. I tried plugging it into another USB port (as suggested by Windows Help Center) but that still didn't work.

It's not often that something like this gets me in a circle and scratching my head but I'm really starting to run out of ideas.

--Love the website motto: [stupid questions are easiest to solve.]

I am running Win7x64 on a newly installed (non-laptop)
MSI ZH77A-G43 motherboard with i5-3570

I spent a couple of days ensuring that I had installed all of the drivers
including the chipset, facilitated by MSI's LiveUpdate5.

I have a simple USB thumb drive.
I take it to my roommate's (VISTA) computer--it plugs in just fine. I cleaned, rewrote, read.
I did a check for errors scan; in properties, it is FAT formatted with default allocation size (2056).

I plug it into my computer (detailed at top). I am not even getting a common problem--"unrecognized USB device."
It does not even know that it is USB apparently--I get an error box from the system tray:
TITLED: Driver Software Installation
Device driver software was not successfully installed.
----
unknown device (fat red) X Device unplugged
unidentified device (fat red) X Device unplugged
----
[nonsense help links from MSFT] CLOSE box

SIDE-EFFECTS:
There is a small led on the thumb drive that shines steady.
(assumably indicating something is wrong; nevertheless power is present)
(normally, it flashes on and off a couple of times when recognized on VISTA computer.)
(yes I tried multiple USB plugins, on front and back of tower-case)
I hear an audible "g-dunk" sound every 1 second.
The Device Manager window, though functional and operational, briefly flashes
in response to every g-dunk (a 1/2 second later.)

Greetings folks

I have a problem that bugs me for years, I never intentionally solved it, sometimes those errors disappears and all USB ports work fine, sometimes they do not. So anyone can help me please, it would be great.

Some of my ports do not work all the time, I cannot identify a specific moment. Inside the Device Manager, Universal Serial Bus controllers, I get 1, 2 or more "Unknown USB Device ( Device Descriptior Request Failed )", sometimes more sometimes less.

CPU: Intel Core i7 3770
Motherboard: AsROCK H77 Pro4/MVP
Windows 10 all available updates downloaded and installed as of today, and everyday. The problem appeared on Win 8 or 7, not sure when. So it's not necessarily Windows 10 specific. I ported it to 10.
Here is what they look like:
http://prntscr.com/d6rm6k

Bios is up to date. Chipset drivers updated, various solution tried from googling, I even managed to make all USB ports stop working testing some of these solutions, I had to restore windows from a ghost image I had.

It's like these USB ports remain suspended sometimes.

Any advice on what to try? The most annoying part is that from the frontal USB ports some stop working randomly too.

Thank you

Hello everyone,
i hope you can help me sorting out this issue that is causing me a hard headache at the moment.

I've bought this new Lenovo Z50-70 laptop with windows 8.1 preinstalled on it. Fresh new.

I'm trying to connect via usb a guitar audio interface (Line6 POD HD500) so i installed the drivers via the .exe setup file i downloaded from Line6's site.
The device worked fine on my previous HP pavilion with windows 7.

Now when i completed the installation, i connected it and i had this error:Windows has stopped this device because it has reported problems. (Code 43)A request for the USB device descriptor failed.
I used slimdrivers to update all the other drivers, in case it was a conflict causing the error.
I checked via command prompt with command "pnputil -e" and i saw a driver from the vendor of the device listed, so it is installed correctly i think.
I tried all USB ports i have, 3.0 and 2.0 on one side of laptop and 2.0 on other side.

When on device manager, if i click update drivers and choose the "let me pick from a list of device drivers.." i don't see the company name of the device.

i saw that another guy posted a really similar problem on SevenForum and he figured out how to force windows to use the drivers but he didn't post the solution.. Here is the post: Can't get Windows 7 x64 to use the drivers I've installed repeatedly Solved - Windows 7 Help Forums

Hi,

On a fresh clean Windows 8 image, my software driver (signed) installs fine and shows up properly in the Device Manager. However once i uninstall it , subsequent reinstalls show up as 'Unknown Device' in the Device Manager.

From the device details, I find that it refers to /looks for the .inf file in c:\windows\inf folder but the file itself is missing from the location. The FileRepository has all the required files. But trying to update from there also fails.

Could anyone help me with troubleshooting this problem. What could be going wrong.

Thx,
Gita

That dxdiag "no sound card" message is misleading as I've found it says that if no driver OR sound card. I think you're missing the right driver

Also, it would seem from your post you have High Definition (HD) audio. Which means you'll need to find the right High Definition audio driver. (AC97 pre-dates HD audio so the Realtek AC97 couldn't be right)

Try starting on the HP support website HERE and enter your model number or they have a button where they'll try to identify your product and drivers for your model. They should list an HD audio driver there

Greetings,

I'm running Home Premium 64 on a Sony Vaio Laptop (CS170F). I'm having a curious problem: Yesterday I plugged into the machine the dongle of my wireless logitech mouse, and for some reason the machine said "Your unknown device is ready to use" (my OS is in spanish, the messages may not be accurately translated). Since then, an annoying message pops every few seconds warning about an "unrecognized USB device", that "didn't work as expected". The best part is this, if I click on the tray icon, sometimes the informative dialog window is emply, an other times shows all the USB ports in the system plus one extra with a "unknown UBS device", even without any device plugged into the system. I've tryed removing the unknown device from the device manager, but it shows up again.

I'll really appreciate any pointer, link or suggestion.

Thanks in advance, and best regards.
Antonio.

A:"Unknown USB device" without any device plugged

Hi antonio and Welcome to the forums.
Connect the wireless dongle and then update windows to see if there's any generic driver available from Microsoft.

My HDD crashed and I didn't back up my drivers, I got all of them from the lenovo support site for my Lenovo Y570 and still remains "Base System Device" drivers. I've tried the Lenovo Update scan thing and searching google for people with similar problems, I came up with nothing.

So I ask here, what are these drivers? Where can I find them?

Pic below is device manager; in properties it states location as PCI Bus 10 (I have no idea what this means or if its relevant)

I can't notice anything wrong with my Laptop as it is now, everything works (I haven't tried gaming, except I can no longer scroll with my touchpad, the sides used to allow me to but now the whole area of the pad is touch to click)

Thanks for your help in advance would be a huge help if you could help me work this out.

Most of the threads on this error are old, (2015) so I am starting a new one. I only notice it when I happen to be in the device manager. I have no problems with any of my connected USB devices (that I have observed).

I have tried uninstalling it, and rescanning and it pops up again, so apparently it is something that is connected. Without disconnecting All of my USB devices one at a time (which I am wont to do, as it is not bothering me, other than that it is there!) It has been there for quite a while, so apparently is not anything new being connected.

Is there no way to identify WHAT is connected to this port, or even what port it is?

BTW, it only shows up in the USB Controller section, no matching errors in any of the devices themselves!

- 500W Antec power supply

My boot loader is grub2 with a nice custom boot menu using this background image.

The issue is the Seagate drive is listed as an "unknown device" under Windows 7 Ultimate OS (along with 3 other volumes) despite the fact it works OK when I boot Windows 7 Home Premium. Haven't gotten Windows 10 to boot yet, so don't know about that, but its just fine under all of the Linux OSs too.

Described here. I have a problem with finishing work on "unknown device". For a moment, after installing from the DELL (www.dell.com/.../advanced) driver "ST Microelectronics Free Fall Sensor Driver ", file DRVR_WIN_R309372.EXE Device Manager has stopped showing that there is an" unknown device "in the configuration. After updating to "ST Microelectronics Free Fall Sensor Driver", the Chipset_Driver_RCHTX_WN_2.00.10.34_A11.EXE file, from the same DELL page, again appeared in the configuration unknown device.
I decided to remove the ST Microelectronics Free Fall Sensor Driver from the system via the Control Panel to install only DRVR_WIN_R309372.EXE. Unfortunately, the installation can not be resumed, the message "Found incompatible installation of, Version. Please uninstall it via Control Panel Add / Remove Programs before installing this version of Accelerometer". The problem is that Control Panel no longer shows this application. Suspecting that there were some traces left after the previous installation, I tried to remove them from the File Manager and also edited the registry. In the registry I searched for: "R309372", "RCHTX", "Microelectronics", "AccelerometerP11". I deleted the entries containing the above characters. I would be grateful for directional guidance on how to proceed further. I am using Windows 10 64 bit Dell Precision M4500.

A:Random BSOD, "Unknown Device" error in perfmon

About 1/3 of these crashes are blamed on memory corruption directly. Some of the others indirectly.

These crashes were caused by memory corruption (probably a driver). Please run these two tests to verify your memory and find which driver is causing the problem.

If you are overclocking anything reset to default before running these tests.
In other words STOP!!!

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

Any errors are indicative of a memory problem.

If a known good stick fails in a motherboard slot it is probably the slot.

Using Driver Verifier is an iffy proposition. Most times it'll crash and it'll tell you what the driver is. But sometimes it'll crash and won't tell you the driver. Other times it'll crash before you can log in to Windows. If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.
