Nunchuck conflicts with motion plus

[cipitaua]

In my system (ubuntu devel) I get that nunchuck does work only without motion plus. When motion plus is connected (or integrated) alongside nunchuck, both nunchuck and motion plus data are ignored.

Note that I have compiled xwiimote from github repo.

no one?

I have two MotionPlus adapters. The first one is working fine, the second one behaves as described here.

I found 2 indications that my second device is not a genuine MotionPlus but a clone:

1. The screws have Phlilips (cross) heads; original MotionPlus screws have triangle heads.
2. The colour of the plastic inside the small connector that is plugged into the Wiimote is black; on the original MotionPlus it's white

udevadm monitor -k shows different behavior for the affected MotionPlus adapter:

• Plugging the MotionPlus adapter without Nunchuck into the Wiimote causes 2 add events (one for inputX and one for inputX/eventY; unplugging causes 2 remove events.
• The same happens for the Nunchuck alone without MotionPlus.
• When the MotionPlus adapter is connected and the Nunchuck is plugged into the Wiimote, udevadm shows
  • 2 remove events for the MotionPlus adapter
  • 2 add events for a MotionPlus adapter
  • 2 add events for a Nunchuck
  • 2 remove events for the Nunchuck
  • 2 remove events for the MotionPlus adapter

My guess is that the kernel module runs into an unexpected situation and thus removes the devices. To confirm this, a hid-wiimote module is required that is compiled with debug support.
