  • Can you try the steps in the TechNet article "Code 43: Windows has stopped this device because it has reported problems" and let us know if this helps you.

  • There are a few more things to try in this blog post. Does this drive have it's own power cord, or only a USB connection? Have you tried a different USB port or a different USB cable? Have you checked the manufacturer website for possible driver or firmware update?

    Also, have you tested it on another computer since this problem developed?

    Thanks,

  • yes it has it's own power cord but some times it cut's out so that might be the problem

    I have tried different ports still does not work

    I have looked on website for updated drivers for the hard drive I have - going with the label says it ROHS but that's all I have

    I have had this for 3-4 years

    my daughter has been using it on her laptop but says it keeps cutting out

  • Hi,

    To be added, please also try to connect your external drive to other computer for test, make sure this problem not caused by hardware problem.

  • Hello,

    I am having a similar problem but not the same i guess.

    After i updated my Lenovo G580 20150 to Win 8.1 all 3 USB ports stopped working. Now i can't use any USB device (Mouse, Flash drive, portable HDD etc, all working on my other 3 Win8 computers). Below are some screen shots for further information.

    Please help to resolve this issue.

  • go to device manager, right click properties of usb device, powermanager, uncheck poweroff

    Also right click start, goto power, in the power options change usb powersaving feature.

  • Many thanks, I had exactly the same problem as gemmazak, even down to the same laptop and OS, and this suggestion seems to be the solution.

  • These functions and menus do not exist on Windows 8.1 now, they may have before. I tried every possible menu and sub-menu in the USB sections but nothing for power. Getting tired of Windows inventing errors, device is fine, driver is fine, ports are fine, Windows is not fine. How soon to an Android OS. lol

  • In my case, it turns out that the USB cable was the problem.  I'm using a mini PC that has the DVD player stacked onto it and a very short jumper cable (Lenovo ThinkCentre M73).  I was using a cheap USB extension cable to relocate the DVD away from the PC.  This worked for some time but perhaps a new driver or update came along and it no longer worked.  I tried another DVD player (identical), a different extension cable, same results.  As soon as I stacked the DVD back on the PC and used the OEM jumper cable it worked again.  I verified this again by reattaching the extension cable and the problem returned.  Removed the extension and problem solved.  My guess would be that the extension cable I used was not USB 3.0 compatible.

    Hope this helps someone else.

  • I uninstalled offending item in device manager then I plugged it back in and windows fixed the problem itself.

  • In order to resolve this issue, your device or any other devices you want to connect with this same issue, please do this; Open the Windows PowerShell (Admin) and type: chkdsk /f/r/x. It will inform: 'The type of the file system is NTFS.
    Cannot lock current drive.
    Chkdsk cannot run because the volume is in use by another process.  Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)' select Y then re-boot your machine and follow the on screen prompts.
    After the reboot, again, Windows PowerShell (Admin) and type: sfc /scannow and allow the process to finish.
    Now clean the registry with a reputable program such as CCleaner then take a note of the device/s name and select 'run' from the Windows menu list bottom left.
    Type 'regedit' without the apostrophes and open the registry.
    Select 'Edit' then Search... and type the brand name of the device in the search bar.
    The search results will point you to a series of strings of the device that was giving the *(device descriptor request failed) code 43* error message.
    Every string in the registry with the name of your device will need to be deleted but ensure it is the device's name from which was generating this error example; Logitech, Seagate, whatever brands device name that has generated this error code!
    Ensure you have removed every last trace of your devices name in the registry.
    Then after completion use the CCleaner again to remove all known traces and re-install the devices software if this is the case.
    Your device will come back to life without the error message and start to work again.
    Reasons why this happen are not entirely certain but often PC's pick up spyware/malware/virus's and corrupt the registry's strings other times, updates and upgrades in particular over lap information and again, corrupt the software and its registration process.

    Good Luck!

  • You're right - chkdsk and the scan process do take some time to complete, but the overall process worked!! My PCs both recognize my phone again, many thanks!! What a huge relief!

    Tuesday, May 30, 2017 9:07 PM
  • I have a phone that is not being recognised. I am not familiar with powershell commands but I tried Chkdsk f/r/x as per example but all I get in response is "The drive, the path, or the file name is not valid."

  • You should be putting in "chkdsk /f/r/x" (no quotes) not "chkdsk f/r/x" you are missing a /

  • If you’re using a USB hub, or have mixed 2.0 and 3.0 USB ports, then, before touching registry, power settings, chkdsk, Power Shell, troubleshooting, and drivers,

    just try plugging your USB device directly into the 3.0 port.

    Worked for me :)

  • Hey guys,

    I found a solution for this one!

    I was using the short black USB cables and they had different errors each.

    One showed the error below "Unknown USB Device (Device Descriptor Request Failed)Unknown USB Device (Device Descriptor Request Failed)

    The second did not respond at all. I've tried these cables on other PCs and it charges the device however it does not open the transfer (import) dialog box.

    I tried the original white cable that is part of the charger itself and it worked fine. The usb connection was recognized by the Android and I was able to transfer my pictures.

    From now on I will not use the short black cables that we purchase and I will use the cable from the charges. Simply detach it from the charger at the wall and you will be fine.
