Hi,

  Is it possible to make Linux to create a separate /dev/input/eventX
node for all the device composited ?

Example: if my device is supporting Mouse, KBD and Consumer

if I want to create three event nodes for each, like /dev/input/event1
/dev/input/event2 /dev/input/event3.

How can I do if I am using bluetooth Smart HID device ? Please share your input.

We have a quirk for that. HID_QUIRK_MULTI_INPUT is the one you are looking for.
IIRC bluetooth Smart is using uhid, so there might be no facilities to
set this without having to rely on a separate (new) HID driver. Check
fo rhte code of hid-generic and just add a .probe function that sets
the quirk.

You could also check with bluez if they do not have anything to split
the HID devices into three (i.e. make sure bluez does not agregate the
devices by default while it should use several distinct uhid devices).

Cheers,
Benjamin

thanks in advance.
