I’ll step in to defend @Jesus_Rodriguez a little bit on this one (no, really… I just hope he won’t start arguing that the products aren’t comparable 
).
The @ALLO_audio_boards USBridge, original version, was based on a SoC that breaks with newer versions of Linux. How old, do you ask ? Well, the most recent supported kernel was released in November of 2013, and if I’m not mistaken, the USBridge was released in 2016… Recent releases of DietPi work on it, but that’s the reason why you can’t have Ropieee on it.
Another, which might’ve changed at this point, is the problems that users were having with Cambridge Audio streamers (CXN v1 and 851), which don’t have Linux USB 2 drivers. So they were stuck with 24/96 over USB from external streamers, because that’s where USB 1 stops, and there are few (if any) windows streamers.
