RS130 McIntosh DA2 DAC not connecting via USB

I have a McIntosh C53 w/a DA2 DAC running firmware v5.02. The RS130 is not recognizing the DA2 DAC via a USB connection. Are these two devices incompatible over USB. I’m currently using coax until I can figure the USB issue out.

We apologize for any inconvenience caused.

Please answer a few questions.

  1. RS130 has 3 USB ports. Is your DAC not recognized even when connected to all USB ports?
  2. Is the USB external hard drive not recognized when connected to your RS130 USB port?
  3. Even if you connect another external DAC to your RS130, is it not recognized?
  4. Have you changed the input setting to USB on RS130?
