OpenCores USB 2.0 Function Core

Hi,

Is there anyone who has experience with the OpenCores USB 2.0 Function Core?

I have to write a driver to interface NIOS, but I don&#39;t know how. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

    I believe the opencores 2.0 core is intended for ASIC implementation; it is impossible to achieve 480Mbps on Cyclone FPGAs; they don&#39;t have the appropriate transceivers.

    OK, tnx. But that&#39;s out of the question right now.

    I would like to know how to initialize the core, open an endpoint, handling interrupts, transmitting/receiving data, etc.
