webcamd already provides support for linux input API for at least one
type of input devices - wacom tablets. There is also preliminary support
for joydev (ulinux at r2494). But a lot of devices including usb joysticks
and non-wacom tablets use hid-core.c rather than their own driver...

And if you mean the approach that can be used by the console driver
there was GSoC 2007, not sure what happened thereafter.
