--Tested remote driving of rover using 4G modem.  Framerate was reasonable (~8.5 f/s/c), but latency was a problem.  Long delay between when action happened and when image was received, which didn't seem to happen when using wifi.  Also a delay between when command was issued via GUI and when it was executed.  Not sure what can be done to fix this--might the problem go away with better 4G reception (i.e., outdoors)?  Image delay might be helped by reconfiguring image streaming code to use RTP over UDP, instead of the TCP it currently uses.  Don't have any ideas yet on how to improve commands flowing the other direction (currently using ssh to send a command to run an executable that talks to the motors).
--Compressed previous backup of SD card in /aux/sbroniko/backup (from 2014-02-03) and initiated new backup prior to changing over to backup gumstix.

--Attempted to test built-in wifi (802.11g only) for remote driving.  Framerate was better than 4G but not as good as USB wifi (got ~10-11 f/s/c from built-in wifi).  Latency didn't seem to be a problem, but the problem of the USB port failing happened much more quickly when USB hub was plugged into main USB host port.  This happened twice in a row, but the third time I was able to get it driving and make a successful loop of EE313.  Also tried with hub plugged into USB OTG port and found the same problem as prevously--get an error message stating (musb_host_rx 1625: Rx interrupt with no errors or packet!) and the capture program freezes until killed.  Pretty sure the USB OTG port is useless.
