Might be the FTDI chip browning out. Going to try to add a cap to the power rails when we get the parts for it

Seems that the webcams were causing problems on the USB chip on the server. We added a powered hub and moved tooltron over to there and the problems have disappeared. My guess is that the webcams were drawing too much power but we're not quite sure of the cause.
