Unknown USB device (Device Descriptor Request Failed)

I am running the Lenovo Ideapad y510p (the GT755m SLI version).

 

I had my USB mouse and my flash drive connected to the 2x 3.0 USB ports (the ones on the left), 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 of the flash drive) to the 3rd USB port (the usb 2.0 port) they both work perfectly fine without any errors at all.

 

I would like to know what may have caused that error and if there is any solution at all.

 

Thanks in advance, Mersif.

Still looking for any type of solution. I think resetting the 2 ports would fix the problem but sadly I dont know how.
