twixx Posted April 21, 2017 Posted April 21, 2017 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?
pmpp Posted June 21, 2017 Posted June 21, 2017 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 .
