Greetings wise wizards of EE:
I'm helping a friend who owns a high-speed Xerox Documate 1120 scanner, which she connects via USB cable (it is a non-network scanner) to her HP Windows 8.1 laptop.
Just recently, when she plugs in the USB cable for the scanner (and the scanner is powered up) it crashes her laptop... the laptop actually shuts down completely.
It crashes when plugging in the USB cable for ALL of her USB ports, and I've uninstalled and reinstalled the scanner driver software & restarted infinitum. I've also taken the scanner to my home and successfully connected it via USB (same cable as used on my friend's laptop) to my Windows 8.1 desktop, as well as a Windows 10 laptop, and neither of them crashed, even without first installing the Xerox scanner driver software.
Thus, the issue seems to be with my friend's HP laptop. I'm not sure how to proceed, however, which is why I need your help. I am assuming it is a hardware issue, but I am not 100% certain of that.
Any help would be most welcome. My many thanks in advance,
