I used a UFO202 recently in Windows 7 - it worked perfectly at line levels.
Now I think about it, I probably didn't install ASIO4ALL and the only
real problem
was getting the mixer to select the correct device. The first time I
tried it
I was recording through the laptop's microphone instead of the UFO201's
line-in.

I'll try it again next week and make some notes.
