SimHub not recognizing External Sound Card

I've had my system set up and working for a while, but suddenly I can't get all channels. SimHub recognizes that there are 8 channels, but only if my sound card is plugged into one specific USB port, any other port it only sees 2 channels. 

Even though the external sound card is plugged in it's stating:

"This output is your current Windows default output, it's strongly recommended to use a dedicated output/sound card" 

I uninstalled the USB driver and let it reload, no change. 

Any suggestions? 

Thanks
