    Dell U3011 SD card reader U/S after fall creators update

    I have a Dell U3011 monitor which has an SD card reader. Since I installed the fall creators update (Win10 x64 Pro), the card reader is no longer functional. I've tried multiple SD cards, and none of them show as a drive. When I look in Device Manager, under USB Controllers I see "Unknown USB device (Device Descriptor Request Failed)".

    The PC is dual boot with Ubuntu, and when I boot Ubuntu the SD card reader works, so the problem is not with the hardware. Any suggestions on a fix? I use the card reader fairly frequently.

    Win 10

    Uninstall the "unknown USB Device" in the Device Manager, then restart the PC and see if that fixes it. Many times with devices such as this the uninstall and reboot will fix it.

    One possibility, that I've seen commented on, is that some older hardware will no longer be supported. Dell only notes support up to Win 7 for the card reader which could be an issue. May not apply to this but something to consider.
