NIOS-II and USB

Tadaaa...

Perhaps there's a typo somewhere, or perhaps I didn't read carefully enough

Slave Mode both speeds:

J3 = Open

J4 = Open

Full Speed:

J5 = Open

J6 = Closed

Low Speed

J5 = Closed

J6 = Open

I deduce the Fullspeed/Lowspeed by the presense of Low Speed Keep Alive Packets in the Stream.

Now all I need to figure out is how to get the USB interrupts. I do this:

alt_irq_enable_all(USB_IRQ);

alt_irq_register (USB_IRQ, NULL, handle_USB_interrupts);

Is that all I need, or... http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif
