USB-B port question

RS150B: can an external CD transport be connected to the USB-B input on the RS150, or does it need to be connected to one of the USB-A inputs instead?


The Hi-Fi Rose device must only be connected to USB-A when connecting a CD player or CDRom.
When connected to USB-B, it is not recognized.

Another problem related to USB-B.
If I connect RS150 to my computer as sound card. I do not see on the screen the frequency and file type (PCM or DSD). In other DACs like eversolo and matrix and IFi I do see this information.
How can you fix it?
