My USB ports stopped working a few days ago. I'm guessing it was probably connected to the unscheduled checkdisk which deleted a couple of corrupted files pertaining to a USB Disk Security program. Now the USB ports don't work like they should; my mouse lights up when I connect it to the laptop, but doesn't work. The prompt says device is not recognized, or something like that. I already uninstalled the USB Disk Security program but the ports still don't work. How do I get them working again?
