Ok, i now figured out that the "USB" on the DE0 board is only for JTAG/flash use. In the schematics i could see that the usb blaster is actually realized with an FT245BM. So, ok seems no really useful fast usb transfer with the DE0 board.

In our design, we would like to have smth like a fifo-usb interface, if possible even without instantiating a whole nios-ii soft processor.

So my question still is, is this possible with the DE2 board, or is it necessary to purchase a dedicated usb ip core? And from the pc side, does it work with libusb?

thx a lot,
