Maybe alsa-tools has what you want? It mentions this: "us428control -
Controller utility for Tascam US-X2Y".

us428control! Didn't knew that one. Tried it out, immediately:

:~$ us428control
us428control: US-X2Y-compatible card found on hwdep hw:1
mmap failed:: Device or resource busy
us428control: no US-X2Y-compatible cards found

Strange.

Another problem: About every second time I connect the US-122, my laptop
crashes (frozen graphics) and I have to reboot.

If my system doesn't crash, journalctl says:
