Help from experience builders om mcp modules of opencoptits

My name is Paul i am from Portugal and i build a MCP using OC Bord's
1-master card
1-usb expansion card
2-iocard displays

Software

FS2004 + fsuips

I make all the connection of all swith displays etc... is working fs2004 default planes but my idea is to work PMDG 737 wilco Level D using usbkeys emulator from oc but i have read that some off the component like on off switch dont work usbkeys emulator is that true?
And the push baton connect to the mastercard input cant be connect also to usbkeys emulator? to put MCP working all of the planes and overuse using deferent config of sioc .

Sorry for my poor english

best regards
Paul

BTW: for the Level-D you should not use the usb key emulator. Use the Mastercard, my SIOC scripts for the Level-D MCP and my free leksecon program that connects SIOC to the Level-D via its SDK, see http://www.lekseecon.nl/lekseecon.html
