[libhid-discuss] Using libhid with composit device

[Ali Asad]

Peter, thanks for the prompt & to-the-point reply, and for keeping my hopes up. I will investigate further and see if using libusb provides a faster path for me.

regards,

Yes.

I think neither is the case.

Linux certainly allows userspace programs to detach only a single interface out of several implemented.

But, you may have to program libusb or even usbfs directly, and not use libhid.

But it may also be a simple fix for libhid, allowing you to continue using libhid.
