NanoPi NEO air usb hid gadget

1 post in this topic

Dear community.


I like to get the NanoPi Neo air work as HID Gadget using libcomposite.

I am using the dev kernel (4.10) and libcomposite is loaded.

Following this tutorial the usb gadget init script is running without errors on startup.

But there is no entry in /sys/class/udc/ and i get no /dev/hidg0 device


Did i missed something? is there a special overlay directive for the usb controller? or is something missing in the kernel?

is it better to use the g_hid module?
