AFAICS, things should ideally work this way: plug USB adapter, ALSA uses its default USB-Audio.conf settings (just like with several other PCI and such cards), then for devices with non-existing H/W volume (and only those!!), automatically and generically provide ALSA softvol.
The "automatically" is easy to write but hard to achieve the guarantee to work with all possible devices :)
Especially the mixer name of usb-audio is determined dynamically by guess from usb descriptors, covering all possible names is no easy task.
Oh well, I'm not entirely up to what you're indicating here, but at least I do have some diversity, via two very different adapters (one 5.1 / H/W softvol, one not), and thus I should be able to draw some conclusions.
Thanks!
