How to make fbdev backend of wayland work under LinuxKernel and Busybox?

[binnan hao]

The target system is a mini Linux system (LinuxKernel and Busybox), backend
is fbdev. I got following warning and cannot operate keyboard and mouse.
Could you please tell how to make fbdev backend of wayland work under
LinuxKernel and Busybox? There is not such issue when running Qt4 and both
keyboard and mouse works.
warning: no input devices on entering weston. possible causes:
- no permissions to read /dev/input/event*
- seats misconfigured (weston backend option 'seat', udev device property
ID_SEAT)
