On that note, here's a helpful hint for G-series users. In the Logitech G-series Key Profiler software, go to Edit, All G-keys, Disable.

Note that any time you unplug your device (including power off), the Logitech device will reset to hardware defaults. You will need to run the Logitech Profiler software to load your settings back into the hardware! (and then close it again)
