Allo USB Bridge not recognized in Volumio

I installed Volumio 2.348 on my Allo USB Bridge (microSD card)
but it could not find the USB Audio if I use the USB Bridge port.
I tried other USB ports on Sparky and they all work fine.

I switched back to the original eMMC (with Dietpi installed) and
it has no problem recognizing the USB Bridge port so it seems
to be a software issue.

I googled around but could not find any clues on how to troubleshoot.
