[RWP] Does Behringer U-CONTROL UCA222 have internal drivers?

[Indigo]

I just tested with my $10 thumb drive sized USB device, and the Asus 
Xonar soundcard is definitely failing to provide speech, when the little 
USB device does work for speech.
I'm wondering if the Behringer U-CONTROL UCA222 has its own internal USB 
drivers, or does it use the Microsoft Generic USB Audio Driver?
The little $10 USB device really has independent internal drivers, so 
sometimes will work at very low computer levels, when nothing else would 
provide speech.
It's just crude sounding, and invariably comes on at ear-splitting volume.
The $30 Behringer U-CONTROL UCA222 at least has its own headphone volume 
control, and claims high quality ad/da converters.
I wouldn't expect those to be fantastic, but if it'll be totally 
reliable for hardware speech, it'll do.
So, my only concern is whether the U-CONTROL UCA222 has its own internal 
drivers or uses the default MS generic USB audio driver?
Thanks for any help,
