A request for the USB device descriptor failed. how to fix?

Derek September 8, 2015 at 15:01:16

After Uninstall in Device Manager and restart does the error still show? There is some very general info here: https://social.technet.microsoft.co... Was there an error code? Have you tried other USB ports (eg. USB 3.0 instead of 2.0)? Always pop back and let us know the outcome - thanks message edited by Derek

The descriptor is what tells Windows what the device is and what, if any, drivers need to be installed. The device is not giving Windows the description of what it is. Does it show up as an external drive in Windows Explorer? If so you should be able to copy and paste file to the device. If not, I would suggest getting a refund and spend a little more on a name brand player. You get what you pay for.

Yep I did mean restart the computer but I expect you've done that several times by now. THX 1138 is probably on the right track. Always pop back and let us know the outcome - thanks

That reminds me of the 'media descriptor byte' that floppy disks had to have to be seem by windows. If it wasn't there windows would claim the disk needed to be formatted.

This usb player has a 8gb micro sd. should I reformat it then?, no drivers came with it. Only in device manager do I see it with a yellow icon next to it.uninstall reinstall or even update driver(which says driver is up to date) doesn't work Manufacturer: Asus Model: M11bb-ca002s OS: Windows 8 64 bits CPU/Ram: AMD Quad-Core A8-5500 3.2GHz/ 6gb 1600MHZ Video Card: Radeon HD 7560D Graphics Sound Card: realtek

Re #6 You say "doesn't work". When you right click the item with the yellow icon and select Uninstall does nothing happen at all, or do you mean doing so doesn't cure the problem when you then restart the computer? By the way, if it asks whether you want to uninstall software when you do this say NO. The idea is to let it find new hardware (after restart) which then sets up the existing software again. This procedure is quite different to what you normally expect an uninstall to do. When the micro sd is inserted and the mp3 plugged in, does the mp3 player show up as a drive? Always pop back and let us know the outcome - thanks message edited by Derek

does not show up as a drive. only shows if I go into device manager with icon. I did uninstall, then reinstall. also did update driver but then it says driver is up to date. several restart since then still not corrected Manufacturer: Asus Model: M11bb-ca002s OS: Windows 8 64 bits CPU/Ram: AMD Quad-Core A8-5500 3.2GHz/ 6gb 1600MHZ Video Card: Radeon HD 7560D Graphics Sound Card: realtek

What does it call the entry with the yellow error? Always pop back and let us know the outcome - thanks

it says : unknonw USB device (device descriptor request failed) then Under properties: Windows has stopped this device because it has reported problems.

Presumably you did all this (sounds like it): https://technet.microsoft.com/en-us... Have you tried the mp3 in another computer? If it doesn't work there then it looks like THX 1138 is right and the mp3 player is faulty. You could always try formatting the micro sd card (if you have some device that can do so) but I don't hold out too much hope. Always pop back and let us know the outcome - thanks

yes Ive done those steps before posting the question here. Manufacturer: Asus Model: M11bb-ca002s OS: Windows 8 64 bits CPU/Ram: AMD Quad-Core A8-5500 3.2GHz/ 6gb 1600MHZ Video Card: Radeon HD 7560D Graphics Sound Card: realtek

Formatting might remove the configuration or software that makes it a mp3 player and not just a USB drive. But maybe at this stage you have nothing to lose.

nbabe September 9, 2015 at 16:43:11

ok I dit reformat it. as I said earlier the micro card is recognized by computer if alone. but if in the mp3 then its not working.

Then I reckon the mp3 player is faulty or it needs drivers. Without a brand name it is impossible to find drivers. There are plenty of driver websites about but most of them are either useless or scams. I'd try to get a refund, otherwise cut your losses and get well known brand. From #3 onwards we've pretty well been going round in loops. Always pop back and let us know the outcome - thanks message edited by Derek
