I have a abit SAR6 MB and Antec Overture. I plugged the case's USB wires to my onboard usb then plugged in my USB drive and windows said it was "unknown device" i left it in hoping it would figure it out.. then after a few minutes it got hot so i took it out. I put it in another computer and it wouldnt work
Im returning the USB drive but how can i fix the ports so it works? 
edit: it was a usb flash drive
