hard to find a good headset that is 7.1 great sound and not usb. but if need to use self powered usb hub is a problem, then lots of joystick would be a problem too.

Why do you want a headset that has to use a USB sound card to generate 7.1? Get a good 7.1 sound card and some great non USB head phones and you will be blown away. I was given a Sennheiser Pc360 for Christmas and they are simply the best I have EVER used in any game PERIOD! They are comfortable, firm placement on the head without being too soft or too hard; easy to attach Track Clip Pro from TrackIR to, not to mention having some serious speakers driving the sounds in them. I have played FPS games and used many of the different sound packs in Aces High and they all sound great. I had a PC150 USB based headset from Sennheiser and have had a Logitech USB headset and once I got a real sound card I never looked back in using a non USB headset.
I use my headset for music while working and games and after using headsets from Logitech, Creative, Turtle Beach (still one of the best sounding ones I think of those three), Plantronics and Sennheiser....I will never go back to any of the previous versions.
