Linux support to USB headset

On my dashboard, I can chose the headset (for speakers and microphone) on the right side of the live video image of me. When I run a test call ( Troubleshooting), however, no option is given to use the USB headset. Of course, I get the audio out through my speakers and it uses my laptop microphone. Should I expect this will change in an actual call?

I think I have ruled out browser issues (Chrome and Firefox) because the settings in my dashboard work just fine.
