I looked at your previous email, and it seems that we both have exactly 
the same problem. I will have to look into this further, because I think 
it is better to get usb dongles working, than just use different 
hardware. As you have already tried it in windows and it works, I will 
proceed with that assumption, as I don't have windows to test with.
The "hstest" program in it's current state would never handle full 
duplex, but at least I can maybe get the recording working.

I am using a USB dongle. Mitsumi WML-C52APR, contains FCC ID: POOWML-C06
