Nexys 4 - how to implement non mouse/keyboard USB device


I have a Digilent Nexys 4 board with me, and a medical device that provides streaming data via USB slave out, and I understand that my board has a USB HID, but it is connected to a PIC uC which converts it to PS/2 signal for me to use it. I was trying to implement a PS/2 controller to read this but then I came across this post on your forums where a Digilent technician said that video cameras are not supported, only mice and keyboards are.

So I'd like to know how to connect a non mouse, non keyboard USB device to my board. This isn't an easy thing to Google so apologies if the answer was in the open.

Wouldn't that require the medical device to have an "on-the-go" USB interface, allowing it to be both master and slave?  I would find that ... unlikely.


Another possible solution would be to get a board with a proper USB host interface, such as the ChipKit boards.  You could then interface that to the Nexys-4 if you wanted, but ... you'd still need a board with a proper USB PHY.


P.S.  I was originally going to propose building your own low-speed USB PHY with the Nexys-IO ... then I read about what that would entail.  (Yikes!)  Cheaper/easier to get a board with the PHY on it that you need.
