(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. >Do you see these problems during boot or during attach after boot? > >The state machine is a nifty mechanism where you start a USB transfer >and when it completes you handle the return value and start the next >one.
