DE2-115 USB DEVICE Demo not working

Hi all,

I just started trying to use the USB port to communicate from the PC to the DE2-115 board. My needs are to transfer info back and forth for the control application running on the FPGA.

Since I never used the USB I figured it would be easier to start from the example provided in the CD but I can`t get it to work.

I managed to compile the project on Quartus and the software code that runs on Nios II on the Nios EDS (FOr versions 12.1 and 13.1) In both cases and even on the already compiled .SOF end .ELF that comes with the demo, it returns the same messagem (copied below) when they run. I couldn`t figure out how to work from that.

Did anyone get this example to work?

Thanks

Renato
