Yeah, that's how it is supposed to work. Seems like the new Wii
Remotes require Authentication. I will push the changes to
bluez-upstream so bluez-5.0 (the next release) will include them.
Thanks for testing!

Yeah, that means the device isn't listed in "hid_have_special_driver".
Therefore, the generic driver picks up the device.

I really wonder why that worked. Maybe there is some user-space code
that rewrites the PID/VID under some circumstances to the old Wii
Remote values or your Wii Remote uses occasionally the old values when
using auto-reconnect. I have no idea, but I actually don't care that
much, since as long as we add all IDs, we are on the safe side.
Anyway, if you see any pattern in the VID/PID selection, feel free to
report these. All the Wii Remote protocol/behavior was
reverse-engineered so we can never be sure that we got it right.

The flashing of the LEDs is a bug. Normally, after connection
establishment only LED1 should be on. You can then change the LEDs via
the sysfs API. Anyway, sometimes LEDs just keep flashing, in which
case I simply reconnect the devices and it works.

dolphin-emu doesn't use this driver. They use their own
implementation, see here:
http://code.google.com/p/dolphin-emu/source/browse/Source/Core/Core/Src/HW/WiimoteReal/IONix.cpp
If it is not working, please report a bug to their bugtracker. I have
never used dolphin-emu, so I cannot help you here, sorry.

How do you invoke xwiishow? If it does not work, please try using:
ls -l /sys/bus/hid/devices/
This should list all connected Wii Remotes. xwiishow just tries to
read these values.
Your system-log looks fine, nothing wrong there. The device is
detected and initialized properly and the sysfs attributes are
created.

That seems fine, too.

Your logs all look fine. If "xwiishow list" doesn't show anything,
then please try:
./xwiishow /sys/bus/hid/devices/<dev>
Where <dev> is the bluetooth address of your device. You should be
able to find this with bash-tab-completion.
Thanks a lot for testing this! It really looks like everything is
working, except xwiishow seems to be unable to find the device via
sysfs, which is odd. The content of /sys/bus/hid/devices/ while a Wii
Remote is connected would really help.
Thanks
David
