Does the bubba support USB keyboards? I do not currently have any keyboard to try this with, but I am planning on buying a wireless keyboard with USB dongle. Ofcourse there is no screen, but that can be handled in other ways...

If supported, what is the destination of the key sequences? The terminal (the same as the hardware serial port) ?
My idea is to make some software that listens to the keys and, if needed for the use case, utilize a network connected LCD for actual visual output (Kiss dp-1500).
