Beginner here. I'm using the freescale usb JM60 demo board tutorial to try and drive an osram intelligent display.I'm trying to use Endpoint 3[bulk] to drive portB and D pins to initialize display and send data. I can send hex numbers to Enpoint three but none of the port pins change after initializing them to one for output.

  Can someone explain how to send data properly to the osram and whats going on in the enpoint buffer? How come my ports arnt changing in debug when I send data to the endpoint buffer?
