Hotas bindings not always working?

[AK2]

My hotas inputs don't always work when in the plane? I mapped the buts/hats ok in, so the game can see the joystick & throttle ok. But randomly some inputs done work?  when I'm in the plane. They could be any input like trim, rpm, water rad,change camera view etc. The axis work some hat switches do and some don't? It's random....

I have no issues with DCS, BMS, Xplane 12. My virpil throttle & joystick work fine.

 

Could this be issue with having more than 8 usb devices?  I currently have 6 devices, but I run my trackir, peddles and hotas via a usb hub the hub has 7 ports but only 4 in use.
