Not to be critical but the information on that sight is a bit thin.
It never explains how one is to learn the names of the devices.  Which
would be required to get the syntax right...

What can I do to get that device name?

Trying lspci, lshw, hwinfo outputs... but not seeing anything really
helpful. 

hwinfo shows snd_usb_audio as being needed, and lsmod shows it loaded.

But where do I look for the device name?
