Hi,
I got the same thing with Samsung G-track device. I replaced its USB cable
for another one and it corrected the thing. You can also try to lower sample
rate and see if it helps a little.
I believe, I saw on Google something about some USB mic with special feature
to reduce/eliminate any noise generated by its USB cable but cannot recall
the name of this mic.
Best,
Pawel.

Subject: recording with imic using a microphone
Hi, Dane.
I just bought a griffin imic which I'm using on my windows xp machine. It is
working wel as far as playback, but when I try to record using a microphone
I get a lot of background whine which sounds like it might be coming
through the usb port. I have the mic gain adjustment turned all the way up.
Here's a link to a sample.

I'm using an audiotechnica modelat8004 dynamic omnidirectional microphone
which has a sensitivity rating of -49 db and impedance of 600 ohms. Do you
have any idea what might be causing this noise. The imic is plutged into one
of the usb ports on my audigy sound card. I also tried it on one of the pc
usb ports on the bcak of the pc with the same results.
