well, if you plug in a usb device and that happens that indicates the hardware completely reset. If it was just a kernel crash then the machine would have stayed hung until you reset/power cycled it. It would have to be it crashed because of the usb device being plugged in, and it would have to be a hw issue since it immediately rebooted. So something about either the device you plugged in or the usb bus you connected to. If this was an add-in card make sure its extra power connection is plugged in. I do have a couple of pci-e usb cards that do not work right on a really old motherboard I have and will (if used with say a usb camera) immediately reset the machine the instant a program opens the camera.
