asterisk users - Apr 2003 - S100U hissing noise..

Hi,

I have got a hissing/humming noise on my handset that is connected to the S100U
USB device..

I was running a CVS version of * that was about 2 to 3 weeks old and had perfect
quality.. But that HDD died on me so I reinstalled and used the latest CVS, now
I have this sound that is best describes as a similar sound to the noise a cpu
fan makes.. Like a high piched hissing noise..

Any one having a similar problem, or can suggest a way to clear it up?

Thanks..

The USB port is VERY sensitive to static electricity. It's not rated 
production quality, only proof of concept. You should really use 
the new TDM400P which supports one to four lines.

I was going to try to se if I could ground it better to get around 
the problem but I got the TDM400 instead.
