AVRdude: How to find port number for AvrIsp MkII in linux?

I am trying to use avrdude from the command line to determine the fuse settings I used on a previously programmed chip.

The command line requires a "-P" parameter for the port that the AvrIsp programmer is on. This port does not show up in the Arduino IDE like a FTDI chip would, and therefore I can't get the USB port descriptor for Avrdude.

Does anyone know how to get this port number on an Ubuntu PC?

P.S. Since posting this I found a more appropriate forum (Avrdude, stk500, Bootloader issues: AVRdude: How to find port number for AvrIsp MkII in linux? - Avrdude, stk500, Bootloader issues - Arduino Forum ) and have posted it there. Could moderator delete this one?
