The problem is that these devices probably use the same one from
Phoenixtec. Supporting this would require creating a meta-driver that not
only detects the USB-to-serial converter, but that also probes which
serial protocol is used.

There really is nothing we can do about vendors that are too cheap to
really embed USB support in their microcontrollers but instead use an
off-the-shelf USB-to-serial converter. Maybe we should drop auto-detecting
these, since there is no way to be absolutely sure what is really
connected, unless they have their own VID:PID combination.

Best regards, Arjen
