USB Audio devices are supported by a single, universal driver in Linux plus a kernel "quirks" configuration file that contains all the specific settings and parameters for various USB Audio chipsets.
If a USB Audio device fails to show up in the output of the command below it could be due to a hardware or power issue or that its not compatible with Linux USB Audio driver / quirks config.
ETA: the UAC2 fix was an old hack to help eliminate audio glitches that were the result of bugs in the Linux USB Audio driver. I don't think its even needed anymore.
