ok, i never blamed the unit just asked if it could, well do you know of anyway it could get disabled cause it doesnt detect anything plugged in, just need a little help.

ok, here is how it goes i won a mx212 at a lanparty, so ya know as most people would they would install it so i follow the directions and plug it in externally, well after i plugged it in i started up my pc, the screen turned on fine, well i get into windows and my usb mouse does not work anymore ...
