It says 4.13.x in nightly kernel builds but i cant still enable g_hid. In this link it says 4.12 would bring usb otg support for h3 boards. Am i wrong? If its still not supported and wont get implemented soon what should i do to implement it? I also read that g_hid should work in legacy kernel but it didnt work with lastest legacy kernel either.  I am trying to get it working for a few weeks now my whole project is stopped because of this.  Its would bring me joy if i could get it working.
