The "$cdev" thing in devd.conf was *not* working.  I don't
remember if it contained the wrong value or if it was just
empty.  It did not work.  Otherwise I wouldn't have to use
a separate script at all.

My wrapper script parses the output of usbconfig to get the
correct device.  That works reliably.
