Remembered that Henrik provided a command to list all devices...
That all lists as float32 is a bit strange... no? I mean the output for speaker...

Yeah, the author will certainly know what formats his device supports natively. Or any user with sufficiently low-level tools which do not need to go through the OS audio layers.
Hm, why involving so many people for such trivial task.... Did you google search for lsusb on mac? E.g. trying https://stackoverflow.com/a/51579385 ?
Thanks!

Excellent, that's exactly the output needed.
The descriptors say that Cosmos has 4 altsettings. Altsets 1-3 of PCM format for 16bit, 24bit (in 3 bytes), 32bit, and an altset 4 of unknown format 0x80000000 for 32bit (probably DSD, but I doubt the ADC can use that altsetting).
That's because you did not specify the VID PID of your device in the -d parameter (as written in https://www.diyaudio.com/community/threads/android-adc-usb-isolation.413723/post-7706383 ) and details of all USB devices were listed.

OK, so should not be a problem with 24 bits!?
Now, I still have "garbled" sound on 16 and 32 bit. 24 was completely wrecked...
How can I trouble-shoot this?

//
E.g. step by step:
1. confirming the device works in a regular OS (like your mac), direct connection, those formats you want.
2. dtto, with your isolation rig
If the above works OK, most likely your recording app has issues. IIUC it implements an UAC2 driver in user space, no easy job, it may be buggy.

1. works 24/384, clear sound.
2. work for 5 seconds at 16/44 somewhat distorted and noise... - nothing at 24/384.
Now the lsusb -v command don't display any verbose info any longer... strange....
