I use XP Home Edition and a USB 2.0 internal card in my computer. USB has always worked fine until recently. Now, whenever I plug in a USP device, XP immediately reboots the computer and then the device can be accessed successfully. Prior to this, a USB device would work fine without causing a reboot. Whatever device I plug in, such as an external ZIP drive or a USB mini-drive, the crash and reboot occurs. I have not recently installed any new hardware or software that should affect this. Any thoughts would be appreciated.
