Problem with HOTAS Bindings changing on their own

[redboot]

My HOTAS bindings (Thrustmaster T16000) keep changing.  I'll reset everything to my liking.  Save the profile, etc.  Then when I come back in to change controls, everything is screwed up.  More often than not, it saves my throttle bindings to my Joystick, so, for example, my Trim disappears and I have 2 TMS settings, one on each device.  I'm tearing my hair out.  User error?  Or broader issue?  Any help would be much appreciated.

Figured this out for anyone having the same problem.  Although it worked fine with the F/A-18 module, a USB splitter doesn't seem to work with this module.  The Throttle ends up getting transposed onto the stick and visa versa.  Plugging the USB cables directly into the computer ports instead of the splitter solved the problem.

The problem with the USB splitter is that it splits not only the data but also the available power. To avoid these problems you should always used powered USB hubs which provide the full USB power (0.5 A I believe) to each USB Out ports. The fact that you did not see these problems with the Hornet is pure coincidence.
