Could a USB female to 3.5mm male adapter transfer my USB Headset from digital to analog audio?

So, I bought the Steelseries Siberia v2 Frost Blue Edition headset for gaming. It's great for playing my PC games, but I want to use it for my xbucks 3-shitty games too. I already have a http://www.gamestop.com/xbox-360/accessories/xbox-360-vga-hd-av-cable/40681 with the VGA plugged into my TV and the Audio Component cables plugged into one of these http://variableghz.com/wp-content/uploads/2010/06/rcato35mm.jpg which is plugged into this http://www.amazon.com/HDE-3-5mm-Female-Coupler/dp/B000E9U9GC (So much shit, I know). So what I'd like to do, is plug my Frost Blue's usb male into one of these http://www.ebay.com/itm/3-5mm-4-poles-Male-to-USB-Female-Tranfer-Cable-Adapter-For12V-Car-CD-Player-AUX-/251232290214?pt=US_MP3_Player_Cables_Adapters&hash=item3a7e9c85a6 and plug the 3.5mm male into the open 3.5mm female from the coupler. I've heard that you need a seperate device to convert digital audio to analog, and I was wondering if this would work; or if I'm trying to do the impossible. I mean, it's only like $5 for the cable; but I'd like to be somewhat sure before I waste the $5. (Gotta save up for those Steam sales ;D) Also, thanks for reading this and an additional thank you to anyone who responds.
P.S Hope I'm in the correct forum. 

Using that adapter would probably be as useful as plugging your ears into the wall to convert your hearing to digital audio...

Hehe, I figured as much. Well, it was a short lived dream. Guess I'll just have to settle for buying a $15 cheapy headset so I don't bother my parents with the noise.
