Hello Everyone...
I've been able to get Mass Storage Boot to work, however there does seem to be a glitch. When I upgrade my SSD card with the command BRANCH=next rpi-update, Chromium looses the ability to play you tube videos ( Iceweasel is still able to play them, and OMX player still works). If I revert the files back to the "master" distribution, then Chromium regains the ability to play you-tube videos.
Thank you.
Doug
