You might be onto it here. I tried a different power outlet with no joy. Same result.
Another thing I've found is if I power everything down, plug in the 2i4, then power everything back up I don't seem to get the hum. If I have everything powered up and then plug the 2i2 usb power in, it immediately starts the humming.
Also, I get lots of USB noise all the time that I do not get from my M-Audio Fast Track. Meaning ANY activity on the PC causes little noises through the speakers, sub-woofer mainly. Just moving my mouse on screen within Reaper or scrolling the mouse wheel, for example, makes a "bvvvvvvt" noise. It's not a problem because these sounds are not recorded though.
