For the last few days my macbook fans would go into overdrive for long sustained periods, after looking at Activity Monitor it showed the culprit was a process named syslogd, i opened up console and there was countless logs saying [0x0-0xf00f].com.carvware.gpcdaemonlauncher Could not get HID event via getNextEvent. #-536870183 (0xe00002d9) over and over, to cut a long story short i tracked it down to Gamepad Companion 2.4. I've since uninstalled it restarted them repaired permissions (going overboard) and it's done the trick now my Leopard is Purrrrrring, just letting you know so as to help anyone else who is having this problem.
