I am trying to install windows 7 onto the laptop ASUS laptop X541UA. I can boot from DVD, but, in the windows 7 installation screen there is no USB mouse detected (laptop keyboard works fine).


It is already plugged into USB 2.0 port. 3.0 port of course doesn't work either. I can see the mouse light on though. This is laptop, no PS2 port.

BIOS version: American Megatrends 2.17.1249
USB legacy support: ON. Otherwise mouse light is not even on.
Secure boot: disabled.


Please help!! Thanks!!
