So I have a Toshiba Satellite P745-S4217 running Windows 8.1 x64 and for some reason the two USB 2.0 ports on the left side will stop registering if I leave something plugged into them when I shut down the laptop. I know how to get them working again; I uninstall the ports in device manager and then select "scan for hardware changes" which will find the ports and set them up again. It'll even set up whatever is plugged into the port after it scans.
My question is why do the ports show up with errors in device manager every single time I shut down my laptop if there was/were something/things plugged into those ports? From my understanding this doesn't affect the USB 3.0 port.
