I recently acquired this laptop, and it has 2 USB 2.0 ports, 1 USB 3.0 port. Both USB 2.0 ports have been working just fine, but the USB 3.0 port seems to not work at all... I have uninstalled and reinstalled drivers plenty of times, but no avail. When I plug in a mouse into the 3.0 port the mouse lights up, but it doesn't work. I've been installing other drivers onto this laptop as well (when I got the laptop it was a fresh install without any drivers), and after one restart the USB 3.0 port seemed to work. But not it isn't working again. Any suggestions?
