USB headset

[John Heim]

I can't find any documentation on using a USB headset in linux. I guess I'm 
handicapped by being an alsa newbie too. Oss had the advantage of being 
simpler anyway. But, well, times change.

Anyway, I have a USB headset from Plantronics. When I plug it in, the kernel 
seems to recognize it. I get the messages about loading drivers and such. 
But how do I get speaku to talk via the USB headset?
