Hi everyone, I made a very simple USB driver <https://gist.github.com/smalinux/3d6a5b000a32b97250b2d0c86b90711b>, but the problem is that the probe and disconnect functions never was called.
What USB device is currently attached to the ids that your driver wants to bind to? Unload/unbind that and then your driver should work.
