I'm can't afford the $2K per year for a unique vendor ID so:

Old USB SPROGs (pre SPROG II) use the default FTDI VID and PID and
should just work with the FTDI drivers as is. They enumerate as a
generic USB serial adapter.

SPROG II usues the FTDI VID and a unique PID (FTDI give out blocks of 8
PIDs for free) which I don't have access to at the moment. These are
blown into an EEPROM along with a description string at build time. It
should enumerate as "SPROG Decoder Programmer" or something similar.

For Windows I just edit the driver .ini files to add the new PID. For
MacOS the PID has to be compiled into the driver by FTDI. I don't know
how the Linux drivers work. Do I need to get FTDI to build the PID into
the drivers?
