The above statement mirrors my experience.

I use an M-Audio USB M-Track audio audio mixer & MIDI interface.

I install PulseAudio and pavucontrol for other reasons, but with them 
installed, I was able to configure the use of The M-Audio M-Track as my 
primary audio device, which it remembers over subsequent reboots.

With pulseaudio and pavucontrol installed, click on:

menu...Sound & Video...PulseAudio Volume Control

Then select your USB device (on the Output tab) as your primary 
(fall-back) device.

If you also use JACK (qjackctl), you'll also have to configure it 
(separately) to use your USB audio device.

Although the keyboard volume control (and task-bar volume control) work 
on an internal audio card, they have no effect on my USB audio (M-Audio 
M-Track) device.  The device itself has volume controls that work for 
it.  Other Ubuntu variants also behave this way.
