Let me ask you a question. How are you gonna plug a USB headset into a sound card?
You can deduce the answer from there, so I won't insult your intelligence. But, yes you can select which sources go to/from whichever sound card (the USB headset is like an additional sound card) in the Windows Sound Control Panel.
Corsair Air 540 + EVGA SuperNova 850 G2 + GIGABYTE Z97X-GAMING G1 WIFI-BK
i5 4690K @4GHz + Swiftech H220 + 16GB Crucial Ballistix Tactical @1866MHz
Plextor M3 & M5 Pro Xtreme + WD Black & RE
Gigabyte WindForce GTX770 OC 4GB + ASUS VS239 (IPS) & Dell P1913SB
custom Mogami cables-->QSC GX3-->JBL Studio L830, Shure SRH940, Sennheiser HD 280 Pro, AKG K260
