I'm working on USB Mass Storage devices (which appears to the system as a
SCSI host), and I've run across an interesting two questions:
(o) How do I determine if a device is 'busy'? That is, if it's mounted or
otherwise being accessed?
(o) How well does the code to handle adding and removing SCSI devices
work? I know it's possible to add hosts easily (which is the current
strategy), but what about removing hosts? Removing devices? What are
the constraints on these operations?
Any insight would be greatly appreciated.
