For all you gents using the G940 and wondering if you caan mod the button colors, well I have found the way to do it and you have teh program in your computer.
It is located in computer-local Disk (C or D)- Program Files-Logitech- Gaming Software- Logitech_SDK_For_PC_1.00.002
it is a zip file and when you run it then you need to open Logitech_SDK_For_PC_1.00.002z ip\ Logitech_SDK_For_PC_1.00.002
Then you run JoystickSDKDemo.exe
Then you can change the colors to either amber red or green. Sorry for the limited colors but thats all i see them giving.
