The MSI motherboard apparently sets the sound card as the first device. Without the sound card installed and the onboard sound device disabled in the BIOS, the USB headset works fine.

How do I reset the USB device as the first device to be recognized? Or how do I disable the sound card without physically uninstalling?

My fall back is to make an old clunker my 'music box' and use the headset on my primary machine.
