I have a USB DAC (currently a Questyle M12, previously an Audioquest Dragonfly Black) connected to a USB port on the Intel 7i5BNH NUC on which I’m running Roon ROCK.
Since the latest Roon software update, the system no longer sees this DAC, and I’m unable to set it up as an endpoint device. Other endpoints on the system are working fine. Both DACs also work when connected elsewhere.
Has something in ROCK been altered to make it unable to see a USB port directly on the NUC it’s running on? I think I’ve exhausted the other possibilities.
The last thing I can suggest is attach the nuc to a monitor and plug a keyboard into the usb port and see if it reacts to the keyboard or is broken all together.
Thanks to all who responded. I moved the NUC to another location, hooked it up to a USB keyboard and monitor, and it worked fine. Still got a problem in the main location, but it isn’t Roon. Tracking down these little glitches is my main occupation.
