Great find! This is similar to my very first contribution to Chirp.
You can see the diff here:
http://chirp.danplanet.com/projects/chirp/repository/revisions/0647f93ebdb4/diff

This was to allow the Kenwood TH-D72's usb-serial device to be
discovered by Chirp on OS X.

I can generate a patch to submit this for inclusion in Chirp, or you
could do it and then it would be credited to your name. Instructions
for submitting a patch can be found here:
