I believe that I had not run into the reported problem because only
recently I began to use the "problematic" USB port for connecting the
web camera.
re: #3 i'm guessing that if mtp was the culprit in this case, it's act
of war should DOS the cam on any port. That's just a guess, though.
re: #4 just for clarity, i meant to look in the log for any
disconnections like you saw with the cam, as opposed to an indirect
observation like trying to copy some files with usb hdd, though you may
have done that too.
