Ok I have a windows xp machine that when I tried installing a new hp printer when it would get to found/installing composite device it would freeze and crash/restart. I have tried install different ways and even installed a new hd with a temp xp to see if it was a motherboard issue and all worked fine. However I have so much data and programs on the other I cant transfer. I have tried updating drivers but not sure if I got the right ones for usb. USB mice and keyboards work fine as do jump drives. I tried plugging in my droid which showed up as a composite device and it crashed as well so I know its not just the printer. Thanks in advance.
