USB 2.0 ISP1761

Hi all! Does anybody use the ISP1761 in a NIOS-project yet? I've heard that there are drivers, but I've never tested it. Is there any experience? Thank you! e-tricky

If you want DMA (sure), you have to design a DMA core and connect the DREQ/DACK. Please read the data sheet and apps note.

But you still need to test PIO mode first. After PIO mode works, then you can try DMA.
