See Lennart's point 3 above. In *your* case it's nice, but apparently in
the majority of cases it's not nice and totally generic which is no use
to anyone.


Cheking your product, it does indeed look like it's missing from the usb
ids database:
https://usb-ids.gowdy.us/read/UD/0763
(as 2012 is missing).

These two ultimately come from UDEV:

udev_device_get_property_value(card, "ID_MODEL_FROM_DATABASE")
 and
udev_device_get_property_value(card, "ID_SERIAL")

So I guess udev puts the underscores in.

PS FWIW, I have a similar issue wiht my USB speakers. I put mine in the
database a while back, but it should be able to get it without this info
anyway.
