Which messages do you see and what mount options are used for mounting the 
FAT partition? I've tried your scenario and I get messages like this:

rsync: chgrp "/media/USBDRIVE/." failed: Operation not permitted (1)

Generally using -a on ext[23] -> FAT transfers is not a good idea, 
because -a implies -rlptgoD (according to man-pages) but FAT does not 
support user or group information, links or devices

I suppose a simplier "rsync -rtv" should accomplish what you need.

You might even want to try unison - it can synchronise two folders in both 
directions, copying newest files from one directory to its counterpart.
