I added a Button Box Interface BBI-64 to my iFly Pro 737 hardware setup and I need to access these 64 switches via FSUIPC4 and the iFly tp FSUIUPC interface. I have read that it should work however only buttons 1-32 show up in the "Button & Switch" dialogue. I have attached the.ini and .log files. What am I missing?

Best Regards, Bob

Native support for > 32 buttons is only available in FSUIPC6 and FSUIPC7. In FSUIPC4, to support more than 32 buttons you need to use a lua script to convert the physical button presses/releases to virtual button presses/releases. There is an example script provided (in the Example Lua plugins.zip file in your modules\FSUIPC Documents folder) called HidDemo.lua that you can use to do this. Update the script to use your devices VID and PID, and make sure the script is running (usually achieved via having it auto-started via the FSUIPC4.ini [Auto] section).
