USB audio interface with inputs on the back

[lilith]

Hi,

I'm looking for a new usb audio interface that will work with linux (Debian 10) without issues. If some extras are not working I don't care . If possible it should have inputs at the back side. I first thought about buying a Behringer, but I wonder if I should not invest a bit more money.

I have a zoom r8 which basically works but it has some problems at high cpu loads when using Jack.

So, i,'m looking for a class compliant interface with preferably asynchronous endpoints and explicit feedback.

Price range up to 400€
2 or 4 inputs
2 outputs
Midi nice ro have
