Actually one more suggestion:
As it stands now, if I want to use this as a permanent solution, I either need to plug and unplug the Discovery Board, or just leave it turned on and running all the time. It would be great if it only turned on whenever my Mac was on. This would require putting a USB jack (or just a DC in jack) on your adapter board, and then connecting the power from that through a switch to the appropriate pins on the Discovery Board. Basically it would be giving the Discovery Board an on/off switch.
For double extra coolness points, you could replace the switch with a single transistor. Connect the collector to the new USB/DC power input, the emitter to the Discovery Board's power pin, and the base to the Mac's 5V line (from either the Mac keyboard or mouse or ADB connector). Then the Discovery Board would automatically be powered on only when the Mac is turned on.
