8000 is the only legal sampling rate for USR.

If you are converting from wav to rmd (as it appears you are), try
something like:

wavtopvf < test.wav | pvfspeed -s 8000 | pvftormd US_Robotics 1 >
test.wav.rmd

I think that's right - if anyone sees a problem with that, give a
shout!  (The syntax works on my box, but I can't test it -- they're
working on the phones today.)
