Comments: *Only works with a USB A hub in between the Pi and the DAC. The hub does not need to be separately powered. Without the hub it has connectivity issues and will not function properly. (It might only be my specific Pi or my specific MX3 that does this). I am using a UGREEN 4 port USB 3.0 hub.
