This is about ease of use . cdrecord in the absence of a device specification
should
query the bus and present the user with a choice of cd recorder devices ideally
if there is one cd recorder it should go ahead an use it if such behavior is
not desired then create an option "--confirm" to ask the user if its okay
to use the "guessed" cd recorder.
camcontrol is a generic scsi command line interface and very nice . What I am
after
is a generic bus enumerator API so apps like cd recorder or fxtv can use
to locate the device in the absence of a specified device.
