Fix USB Device Not Recognized. Device Descriptor Request Failed When you insert any USB Device get the following message “The last USB device you connected to this computer malfunctioned, and windows does not recognize it.” The device manager has Universal Serial Bus Controllers Flag USB Device Not Recognized. Device Descriptor Request Failed First thing i did was check my USB drivers, but there is not problem with them. After that i checked USB port fearing it might be a hardware problem but again no problem found because other devices are working perfectly like my keyboard, mouse etc. The problem occur only when i insert my hard disk, so i thought there must be an issue with my hard disk but again no problem found as it was working perfectly in another laptop. Now i was seriously worried because after checking everything this must be a “Motherboard” issue but i was seriously relived when i found out that the problem is with the Fast startup and USB Selective Suspend Settings are enabled.
