i see the problems: (camera always plugged in at boot)
1. in computerA (messages below) all the time.
2. in computerB, camera functions, but if unplugged/replugged,
the same problems occur upon "camcontrol rescan 0".
(BBB failures, therefore, mount errors).
so i tried commenting out the rescan call in umass.c
after the "if (!cold)" statement, cuz of a possible
bug there, but that didn't change anything i could see.
thanks for your help.
