Common: Get rid of the -S, -V, -P, -T options.
They won't work until after we attach to the backend, but we need them before we attach. Rely on the environment variables instead.master

simultaneously, the backend will choose the first one it finds.

If you wish to target a specific device, you may specify its

serial number with this switch, or using the 'SERIAL' environment

variable. For example, these are equivalent:

The VID and PID are specified in hexidecimal, and the TYPE is
|

the P_XXX enumeration defined in backend_common.h. The '7' in this
|
||||
example corresponds to most Canon SELPHY CP models, and is what you
|

would use if you were trying to get the backend to detect an
|

otherwise unrecognized SELPHY CP model.
