Having problems with rc.local

[jim ruxton]

Thanks Bob,
Tried as you suggested. Not sure that it tells me much. Below is the
info. from /var/log/messages after booting up. and after that what was
written after doing rc.local manually. It looks like in both cases the
uhci info is being loaded identically ?? Do you see anything suspicious.
My camera is on usb 5-1.
