Almost Working: USB ISP1362 DE2-115 without NIOS II

I think I'm almost done with this damn thing. I think I can see the light at the end of the tunnel. I'm sure it's just another freight train, though. So, I've interfaced with the ISP1362. ...

A few questions for you;

1. How are you configuring the ISP1362 without NIOS II; direct HDL, or JTAG-to-Avalon-MM bridge?

Did you check out this project: http://mzakharo.github.io/usb-de2-fpga/

2. What is your test setup?

If you're "cheap", then I'd recommend using Linux and Wireshark. Wireshark can trace USB packets.

If you're "not-as-cheap", then do you have a USB "logic analyzer"? I just purchased a Total Phase Beagle 480 USB analyzer ... for another project ... but since I'm the only one using it, I figured I'd play with USB via the ISP1362.

I don't have any answers for you yet, but it you want to "share" what you've done, then (if I have time) I'll provide a USB analyzer dump for you :)

Cheers,

Dave
