FSUIPC appears to lose focus

[Clutch Cargo]

I noticed this happening with FSX and now with P3D. At the beginning of a flight or even during the middle of a flight I seem to lose my connection with FSUIPC assignments. For example, I will lose my aileron and elevator of my yoke (Saitek). I open up FSUIPC (v4.852), and clear the axis tab, move my yoke a little and it registers. Go back into P3D and I have control once again.

Thinking It could be a hardware or connection issue, I have all my yoke assignments assigned through FSUIPC making sure there is no axis or button assignemtns through P3D. The only assignemnt I have through P3D is the Hat Switch. What I noticed is when I loose control my Hat Switch is still working - just no FSUIPC assignments.

I have also seen this happen repeatedly with my Trim wheel and throttle quads which are also Saitek, if that is relevant. My assignments are set up through aircraft profiles. Could have a corrupt FSUIPC.ini file? I just moved it over from FSX to P3D rather than creating from scratch. Could it be related?

Any ideas would be most appreciated.

It isn't FSUIPC, it's your USB settings. It would happen without FSUIPC even being there. You need to turn off Windows power management on the USB hubs in the PC. Check them in Wndows' device manager -- Windows checks the power management options by default. You need to uncheck them all.

I think for some reason Saitek axes in particular seem most vulnerable to this. I can only think their controllers take more 'juice' than most, and/or don't do something in the USB protocol to keep the things awake.
