Hi everyone,
I need your help!
I have a notebook Asus X54C with windows 8.1 on it.
The problem is: since I upgraded my windows 8 to 8.1, my USB 3.0 stopped to work with USB 2.0 devices.
USB 3.0 devices work well, they are recognized and speed is high, according with USB 3.0 preformances.
USB 2.0 are not recognized. When I plag in my usb pen or my smartphone nothing happen. Only power supply works since my smartphone start charging, but nothing else.
Device manager does not show anything, and if I plug a bootable pendrive, BIOS either does not detect anything.
Any suggestion?
Thanks,
Flavio
