So a CDC device is nothing you could live with?

AVRISPmkII talks a very specific protocol which so far has only been
implemented by Atmel's original device, plus maybe a couple of clones
which try to clone it as best as possible (including VID/PID), so they
are accepted by Atmel Studio.

If you think you have a need to read the VID/PID for that from the
config file, that should be simple to add.  So far, nobody needed it.

Both are meant to work with fairly simple firmware implementations
(based on VDEV).  Again, adding a serial number check might not be too
hard, it's just that these implementations typically don't feature a
serial number.
