USB Expension Cards

Hi again,
After a long pause, I finished the opencockpits expension cards integration. As explained in the documents of opencockpits, I tested all cards and integrated into my configuration. In fact, there are few things to do. I explained the details in my construction page. In my test case, I used USP expension card, one master IO card, one Input Card and one Output Card. They all are configured for "Parking Break" switch on input#1  and output#11 in sioc config file.
Here is a small video that shows its working.
