I have been successfully using the Plantronics DSP-400 USB headset with
both gnophone and iaxComm.  gnophone audio is beautiful and is
apparently a very good client for recovering from stray bit loss, etc.
However, it is no longer supported, even in Asterisk out-of-the-box.
You have to compile IAX version 1 support back in if you want to use
gnophone.  iaxComm is still, in my opinion, quite rough around the
edges.  The audio quality on transmission to another end is very
scratchy and poppy.  I'm not sure if this is a function of CPU power or
the audio system that iaxComm uses.  I've been attempting to use it on
an iPAQ device running GPE.  I sucessfully compiled it and have it
running, but the audio is especially terrible on that device (H3670,
206MHz ARM, 64MiB RAM).  I was able to apply the patch that ziaxPhone
has for the iax2-parser not being word aligned, and that helped the
audio tremendously.  But it's still very poppy, echoy, feedbacky, and
scratchy.  Sort of like lurching through the audio stream.  I've learned
that if I turn the micrphone down to almost nothing it works a lot
better for awhile.  After awhile, though (30 to 45 sec.), the audio
output almost fades to nothing on the iPAQ device.

Anyway.  You might take a look at the USB device available from
www.virbiage.com.  It might work with more than just their FireFly
client, especially if it shows up as an audio device under Linux.
