I have an external USB hub with its own power supply. It introduces a hum when I have its
PS connected.

headphones. Removing the USB connection was enough to stop it.
Good to know. The last mixer I bought I went through channel by channel
and each control looking odd things like that. I would have thought there
should be no analog Audio anywhere near the USB.
