Hi ,

Thank you a lot!

Here is the output from stdout:
UVC: IO method requested is USER_PTR
uvc device is dwc3-gadget on bus gadget
uvc open succeeded, file descriptor = 3

I am using XILINIX Ultra Scale+.

Do you any suggest?

Thank you,

Anything from Github will be a fork, we haven't hosted the project there. In that case (depending on the specific fork) it may be either out of date (because we did quite some work recently) or else contain a lot of work that wasn't done by us. I'll still try to help, but it'll be easier if you're using the main repo since that's the one I'm familiar with, could you give it a try please:

The script looks ok, can you share the output from stdout on the device when you run the application please? What's the hardware that you're running the uvc-gadget program on?

And indeed the options here look like they're from wlhe's fork.
