Description of the feature

Missing hidraw support on kernel

Channel: devel
Build: version 253

Steps to reproduce

Can't use hidraw access on usb otg, it seems it isn't part of the kernel

Expected behavior

hidraw device available under /sys/class/hidraw/hidraw*

Actual behavior

no hidraw class under /sys/class/*

Android switched to Bluedroid in late 2012, Bluedroid doesn't appear to use hidraw to do its work. I believe any other input was handled by Android itself (HAL docs here). For this reason, CONFIG_HIDRAW was disabled on most devices.

You can head over to https://github.com/ubports/ubuntu_kernel_xenial/tree/flo to compile your own kernel and try it out, if you like. If you send a PR with the changes, I can reintegrate them and release a new kernel.
