If your Mac suffers a lockup when connecting a USB device, it is often due to a bad USB device. Or it is a USB device drawing more power than what the port is supplying. Make sure you are connecting it to an internal USB port on the computer, not a keyboard or unpowered hub. If that still causes a problem, see if the device is a USB 2.0 device, your Mac may only have a USB 1.1 port. USB 2.0 devices can draw more power than the USB 1.1 port supplies.
