yes, that was my concern.
there were reports that the S24 series wouldn’t recognize usb soundcard devices, to include the digirig.
one thread here had success with plugging in a usb hub and connecting the digirig to that.
i bought the same hub shown in the picture but didn’t need it with the S25+
(comes in handy as a OTG adapter for other USB-A type cables though. my kenwood D72a data cable works FB)
good luck
