Thanks, even knowing that helps.
I have spent most of this morning soldering a wirewraped USB connector
to my board.
If the interrupt firware was wrong, maybe somebody switched D+ and D- or
maybe I can connect to 2a and use it as a 2nd host.
Unfortunately no joy.
As best as I can tell the USB system is finding 1A,1B, amd 2A - ls
/dev/usbdev* lists
usbdev1.1 usbdev1.1_ep00 usbdev1.1_ep81 usbdev1.2 usbdev1.2_ep00
usbdev1.2_ep01 usbdev1.2_ep81 usbdev2.1 usbdev2.1_ep00 usbdev2.1_ep81

How about anybody used 2A or 2B ?
Anybody know of a Xilinx/Cypres test app that tests hosts on anything
but 1A ?
