If you plug those into the PLAYSTATION, I think it will work. The wiring will be a bit messy and controlling game/voice will have to be done manually.
I don't think the DSS is able to see those little USB soundcards though, only USB headsets like from turtle beach. So I'm pretty sure you can't plug them into the DSS.
My USB keyboard worked just fine with the USB port on the DSS, so there should be no issue with that. Thanks for the help, I'll let you know how it goes. ;)
