...nto that, leaving the ground wire floating, and see if that works. As most desktops have the AC ground pin wired to the chassis, floating the chassis might well eliminate the hum. also, things like fluorescent lamps can greatly contribute to hum, although that often sounds like a buzz. lamp dimmers too, try switching any dimmers in the general area to either 100% on or totally off. > It's an Insignia NS-PAH5101 > It does not have a separate power source, > just plugs for the pink and green sockets. > The cables are pretty thin. > If the problem is shielding, > is there...

...eutral, which is dangerous on its own. As I understand it, GFI sums the currents going into each prong. If the sum is not close enough to zero, it breaks the circuit. >> also, things like fluorescent lamps can greatly contribute to hum, >> although that often sounds like a buzz. lamp dimmers too, try >> switching any dimmers in the general area to either 100% on or >> totally off. No dimmers, but I tried turning off the overhead flourescent lights. No effect. >> not really, the wire itself has to be shielded coaxial wire. if its >> actually the headset itself...

I have setup nut-2.4.1 with the bcmxcp driver for my HP R3000 XR unit and although it appears to work, I receive the following sorts of errors in syslog: Aug 27 10:33:05 sv18 bcmxcp[6373]: Communications with UPS lost: Receive error (data): got 0 bytes instead of 64!!!

Hi gang, Here''s some trivial cleanups that I''ve built up while reading through the code.
