Months ago I bought a Logitech headset for the G5. So far no problems. I could listen to music or use it with Skype. Today suddenly it stopped working in any USB connector I plugged it in. The sound just stopped despite it was selected in the Sound prefs. I tried it on a PB and it works. It has nothing to do with the headset. Is it possible that the USB ports went bananas? To repair it I restarted but the counter kept running forever at startup. I had to shut down, wait a little and restart. It still doesn't work. Paul Moortgat
