I have a lenovo laptop with 2 usb 3 ports and 1 usb 2 port. I recently did a clean windows 7 installation (64 bits os) and noticed usb 3 ports were working only to the speed of usb 2. I downloaded the drivers for usb 3 and installed and it so happened that both usb 3 ports stopped working (not even as usb 2). Then i went to device manager and unstalled the usb 3 host controllers and also deleted the drivers and the result was that both the usb 3 ports were still not working. I tried installing the same usb 3 drivers i had diwnloaded and installed earlier but this time it says, cant installed drivers as system does not meet the requirements.
Now i have only 1 usb port working (usb 2)
Plez help me.....
