I used a USB mass-storage device a while back, for a short time,
it was since removed.
I am chasing some data corruption and will suspect everything
at this point. Any chance that this causes a problem for scsi
devices?
Anyway, I am rather sure that the usb system should keep quiet
as it is not accessed at all.
