Wiim Ultra to external DAC - No USB output option

[Malcesine]

Hi,
I am trying to connect my Ultra to a separate DAC (EE Minimax plus) via USB output.
The music output menu doesn't even show USB as output option, never mind greyed out or simply not working.

I have up to date firmware, tried 2 usb cables, have cycled the power on both devices, have my DAC switch set on USB mode when doing so.

My DAC is a relatively old so not sure if there's a compatibility issue?
I'm using USB 2.0 cables (Minimax is usb 2.0, type B) again not sure if cable compatibility considerations or not?

Coax works perfectly, I'm also using the Ultras subwoofer out.

Any suggestions?
Many Thanks

Make sure your DAC is powered up and set to usb input otherwise the ultra won’t see it.

Thanks...but tried this several times

The It SB options are only available in the WiiM when the USB communication has been initiated. USB 2.0 is fine, so maybe a bad cable?
