Hi @zeb,
Since you’re also experiencing crashing, which is a separate tracked issue with USB drivers, I wanted to alert you to this staff post and a potential workaround: Roon ARC Build 182 Crashing with Certain USB DACs on Android [Investigating]
Please let us know if you are also experiencing crashing in ARC with USB DACs, and not just an error popup regarding device connection.
This issue is potentially device-specific and we want to make sure our list is exhaustive. Can you confirm the particular USB DAC with which you encounter the connectivity popup?
Lastly, for everyone:
Does disabling the USB Driver change these symptoms? We’ll be pulling diagnostics to see how the issue manifests per-device, so if you have it within you to reproduce the error once or twice, please let us know and share an approximate timestamp. Thank you for your help!
