could be that support in the snd_usb_audio driver is not provided anymore
for this device or is not working properly ... and BTW USB is not USB -
there is USB1, USB2 and now USB3

I still think if you don't see the device, the card is unsupported in the
usb audio driver

So I looked for you in the kernel config - it looks like the hid you find
are the audio jack controls, but I do not see the second one.

I think it is a problem with the codec or you need to load SND_HDA_GENERIC
and SND_HDA_CODEC_CMEDIA

perhaps they are not autoloaded

you could also try loading the intel hda driver, it should pull related (if
it succeeds to load without hardware)
