Getting computer to recognize A/D Source


Not sure where this belongs, but I am trying to convert my vinyl to digital files.

My signal path is: Turntable -> Phono Preamp -> A/D Converter -> Yellowtec PUC2 Lite -> Computer via USB cable

I spent the money on the PUC2 because it has an AES in and out on the same box. When I want to play music through my DAC, the AES out works without fail.

When I try to do AES in, my computer has recognized it as a source for two short stints, then fails no matter what settings get changed, system-initiated troubleshooting, or unplugging and replugging the USB cable does at either end.

Any help would be appreciated. Thanks.
