From my experience, the issue is mostly about full-duplex. I managed to successfully use all sorts of cheap class-compliant audio interfaces with the RPi3, but I only ever needed audio output. I never had luck getting full duplex to work in Pd - which I didn't need in the end, so I didn't tried too hard.

This one should work as well, right? It says that its class compliant. https://www.esi-audio.com/products/gigaportex/

i'm not adding anything to the problem solution, but i would like to stress that (from all the reports i heard; and also based on this thread - see for instances Josh's reply), that "class-compliance" is not a *sufficient* condition with older RPis (RPi1-RPi2; and i think RPi3 as well) as these have a somewhat broken USB-controller.
since jakob's target systems are *explicitly* RPi2s and RPi3s, i don't think that all those "it's class compliant, so it should work" comments are especially helpful.
the interesting question really is: can anybody recommend audio interfaces that they have *successfully worked with on the RPi2/RPi3* hardware platforms. without replacing the hardware specs with "a linux system running on an x86_64 processor in an ATX-motherboard with a 200W PSU".
