G940 losing settings

I have a Windows 7 machine. 

I recently got a G940 flight set.  I mapped all the keys in the logitech software AND in AH because it wouldn't recognize the keystrokes I programmed.

Now the problem is that I can go in to the game and sometimes the mapped keys work, sometimes they don't.  I sometimes have to exit the game to get it to work.  Or go offline, then online.  Sometimes it loses the mapping and starts shooting guns instead of flaps etc mid flight.   

I always have the logitech software running when I play. 

All the connections are good and tight. 

Any suggestions?

Sounds like the USB bus is resetting.  That is my best guess.

How would I fix this?  Its an almost new custom built i7 based system.  There is plenty of cooling and a monster PS since I'm running a GTX680.

The size of the power supply is irrelevant.  It has to do with how much current the USB chip can deliver to the USB bus.  It usually is measured in milliamps.

An externally powered USB hub would solve the problem, if that is indeed the issue.  The externally powered USB hubs take thier power directly from the inbound power, not the USB chip.  They can usually supply several amps to the USB bus.

Windows 7 64 bit has a nasty bug when the power levels drop too low on the USB bus, it starts resetting it, over and over again.  I would never run a Windows 7 64 bit machine without using an externally powered USB hub.
