So my question is how does alsa make an scaling for such devices and how to fix it so that the full range can be used in a normal volume spectrum.

I got one more following question, which usb headset and usb audio adapters can I buy right now that are not effected by this issue? Or should I just wait until the upcoming releases that will hopefully fix the problem for all usb audio devices, or is this false hope?

In particular, the Plantronics DSP-500 works well. I've tested it with numerous ALSA releases, from 1.0.14 - 1.0.17 and some post-1.0.17 GIT builds. I've never had a mixer problem with it.

Hmmm, I got some Plantronics USB .Audio 510 Headsets and they are kind of bad. They have wrong dB initialization, incorrect bandwidth allocation when connected to usb hubs but this can also be an kernel usb-audio and/or usbcore bug. And are build out of 3 usb interfaces, 2x usb audio and one hid device (speakers, mic, and not functional uinput keypad) I think I will see if I can get my hands on some Plantronics or Logitech usb headset.
