Wow, that's depressing. Again, anyone know if things will improve with
Jaguar?

It would be nice to get a reaction from apple on this.
"The only current workaround is to connect the iMic through a self-powered
USB Hub. We now offer the Griffin USB Audio Hub, which has helped in many
cases. Some people have had success just by upgrading to OS 9.2.2, but none
of the above solutions works in every case. This is a situation we9re
hopeful Apple will resolve in the near future."
I know there are a few Apple engineers on this list, so could you comment on
Griffen's assertion that this is an Apple problem. I don't always believe
vendors that point the finger!

Thanks Jeff, but in OS X the iMic just uses CoreAudio without any additional
drivers. I'm happy it works for you in OS 9, but we are talking OS X here!

I agree.

Please, someone from Apple - any insight on all this? I really need to do
some recording soon......
Thanks to all!
