    USB device not Recognized And nothing is connected


    Hello,
    I'm about to loose my mind..
    So today I've pluged-in an Arduino device and everything gone great until for some unknown reason my computer just ignored the device and started to pop-up "USB device not recognized" the same device works perfectly fine in my other computer.. after trying, I think, everything, including deleting all usb devices in "dev_show_nonpresent_devices=1" mode.

    Desperately, encourged with a long time's will upgrding my OS, I've formatted the primary partition and installed all clean windows 8 (don't worry, everything is legal).

    Surprisingly enough, the same problem continues, but with a twist, in the device manager I have a persistent "Unknown USB device (port reset faild)", with no external usb connected.

    All the other unknown devices' drivers I've found and updated.

    I have "HP Compaq 6703b" laptop with Windows 8 64 bit.

    Thanks for reading and sorry for my english,
    Hope anyone could help

    Then thought this might be the best solution : Darrell's Write: Arduino Uno on Windows 8 without disabling driver signing
