Quick progress report from Tim and myself:

The smaller of the two chips has been flashed using dfu-programmer 
(v0.7.1 works). It needed a forced erase cycle before it would update

We also reflashed the 2560 with the arduino bootloader using my arduino, 
but cannot get it to talk to a PC directly over USB.

Sending data from PC to the board makes the TX light on the board flash, 
but no activity seen from the RX light.

The only suggestion from us is that there might be a bad connection 
between the two ICs on the Rumba board. Might be something to follow up 
on Monday.

Enjoy the rest of the weekend!
