It seems like the USB drive is generating keyboard events. Hard to tell
what as the system crashes pretty hard.

How can I disable the keyboard events and/or clear the queue? Seems like they
are activated when SDL is intialized and I haven't seen a function to
disable events. If I don't do the waitEvent(), I assume that the events
still get queued up - which doesn't help me any.

Thanks.
