I have included the output of lsusb -v and updated the topic.

snd-usb-audio: probe of 2-2:1.0 failed with error -5
This is related to the line above it:
Nov 29 07:21:21 kernel: skipping empty audio interface (v1) Nov 29 07:21:21 kernel: snd-usb-audio: probe of 2-3:1.0 failed with error -5
which in turn is because of a zero "bInCollection" value in the device control header. I'm adding some sound people to the cc, in case anybody has more clues about what's wrong with that particular device
- I don't personally have any real clue about usb audio.
As the dump in the forum post doesn't decode any of the USB audio specific headers, we'd need to see the output of "lsusb -v" with that device connected.
If the driver bails out at this point, there's something wrong with the descriptors, or the interface has no audio support at all (which would be odd as it could have been omitted entirely in the first place).
We might have to add a quirk for the device, let's see.
