I had my USB mouse and my flash drive connected to 2x 3.0 USB ports, everything was fine until suddenly both of them stopped working. When I try connecting the flash drive nothing happens, however, when I try connecting the USB mouse it says Unknown USB device (Device Descriptor Request Failed) in the device manager, windows error message "USB Device not recognized" also pops up in the bottom right corner. When I try connecting either of them (the mouse or the flash drive) to the 3rd USB port (a usb 2.0 port) they both work perfectly fine without any errors at all.
I am running Windows 8.1. Any help would be really appreciated.
