I would like to improve support for the multimedia controllers from
Contour company, as there currently get relative events swalled by input.c.
The background: Contour seems to have messed up the USB HID descriptions
of their multimedia controller devices in that these report to use
relative axis when in fact they are creating EV_REL events with absolute
coordinate values. The problem here is, that mapping these events to
EV_ABS will break all existing software that supports these devices.
Unfortunately, drivers/input/input.c correctly swallows any relative
events with a relative movement value of zero...
case EV_REL:
if (is_event_supported(code, dev->relbit, REL_MAX) && value)
disposition = INPUT_PASS_TO_HANDLERS;
break;
Simply removing the "&& value" would most probably have adverse effect
on many software. Unfortunately, there is yet no "quirks" handling
present in input.c.
How can I add such quirks handling in a way that would be acceptable by
the kernel maintainers?
Any help greatly appreciated!
