I have a Toshiba Satellite C75D-A7102 running Windows 8.1. Recently, the USB ports on the right-hand side of the machine stopped responding. They do nothing at all when a USB device is connected, including flash drives, mice, and keyboards. The remaining USB port on the left-hand side worked for a couple of weeks after this, but about a week ago, it also began malfunctioning. Flash drives return a "USB device not recognized" error when connected. Wireless mice and keyboards crash the system entirely, returning a USB Bugcode Driver error and forcing an immediate shutdown.
I've reinstalled the USB drivers, run an AMD driver tool to update the drivers automatically, performed a complete factory reset, and verified the BIOS is at the latest version (1.40). Nothing has fixed the problem. Do you have guys have any ideas? Let me know if you need me to post any system information. Thanks!
