I agree. It sound's like a grounding problem. I get the same when I plug my laptop's internal audio output *and* a usb soundcard output connected to the laptop into the same mixer.
Have you tried direct boxes between the soundcards and the mixer? You should be able to lift/drop the ground to kill the hum.
