I can say I have used the BR-20 USB input with:
PC several different systems over the years including a nUC on enhaced power supply.
Raspberry Pi 3 and 4 with enhanced power supply. BR-20 streamer definitely sounds better.
Eversolo A6, A8, A6 gen2 sound very similar as streamers. Will be trying T8
Wiim Ultra that was bought for stereo 2 gave it quick listen and retuned to stereo 2
The Eversolo A6 gen2 is being used as a streamer for more functionality with streaming services. I do miss the volume control that BR-20 provides in Roon.
A problem I have there is the A6 g2 is trigger out to trigger in on BR-20 to power up remotely. The BR-20 boots faster then A6 so need to switch away from USB and back before A6 will detect BR-20 USB port.
Presently use A6 G2 with both a coaxial spdif Cardas Parsec cable and Cardas Clear 1m USB.
Other then what was mentioned above I have never had detection problem beyond above with the replacement BR-20 or previous one.
