Good point. I have a USB volume control (somewhere) and it worked great. There were virtually no issues. It uses the triggerhappy daemon. Below is the help from Audio Config for the "USB volume knob" option.
Code:
Activates the triggerhappy key mapping daemon for USB volume knobs.
Refer to /etc/triggerhappy/triggers.d/media.conf for key/event mappings.
