I think this might be the same issue, if not, please forgive: On all of our deployed XO 1.0 machines, immediately after reflashing, we run one of Mavrothal's scripts that pretty much removes everything from that directory on the XO 1's. The script saves one file only: USB8388.bin If one deletes that file, I believe networking ceases to function. The code he uses is here:
mv /versions/pristine/"$OSVER"/lib/firmware/usb8388.bin rm -rf /versions/pristine/"$OSVER"/lib/firmware/* mv usb8388.bin /versions/pristine/"$OSVER"/lib/firmware/ mv usb8388.bin /versions/run/"$OSVER"/lib/firmware/ rm -rf /versions/pristine/"$OSVER"/lib/firmware/* mv usb8388.bin /versions/run/"$OSVER"/lib/firmware/ The script also removes a bunch of dri/lib,icon 256, and language versions. Frees up about 60Mb on our machines. His full script, along with a swap script, and some bad/ugly installs script is in this thread http://www.olpcnews.com/forum/index.php?topic=4965.15 O, and most importantly, the USB microscopes and Vernier sensors continue to work after deleting all those files. I still haven't been able to get a USB2VGA projector to work on any 11-2 builds even beofre the firmware removal, so I cant comment on that part.
