NanoPi NEO air usb hid gadget

Recommended Posts

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 http://isticktoit.net/?p=1383 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?

Hi, @twixx sunxi roadmap says no support for H3 until mainline 4.12, and best you can have with nightlies is 4.11,  actually only g_mass_storage  / g_serial / g_ether are  working ( i would avoid g_serial it is quite easy to lock )  on legacy and the rest won't ever be fixed if i refer to https://github.com/armbian/build/issues/593 .
