Hardware & firmware flaws - USB DAC

  • a USB C to C cable does not work
  • the DAC does not connect reliably from power off, sometimes needing to be unplugged or power cycled

I don’t have a USB protocol sniffer yet, but I suspect the USB C to C issue is you’re missing grounding on the CC pins.

Hi Joia,

Is there a firmware update yet to fix the problem of the B50 losing it’s DAC connection from a Windows PC?
