Hello Pete,
I'm using Windows7 64bit. I cannot find any options as you described. But I'm using Saitek Cyborg Evo Force. On the joystick there is also a blue light when it is powered on. This light stays on, so I guess the usb device is not going into a sleep mode.
And when I load a specific aircraft, the axis profiles are automatic loaded. But I have to manually load the button profiles by clicking on the check box in the Buttons + switches and key presses menus. When I press on the check box, the correct profile (for instance a 737) is recognized an instantly loaded by FSUIPC. So I don't have to select a specific aircraft profile.
Perhaps I send you the ini file?
Peter
