Comment 28 for bug 1132063

Another note, the xinput utility uses the "XIQueryDevice" (apparently part of xinput2) function instead of "XListInputDevices" (xinput1?) if xinput2 is available. gnome-control-center always uses XListInputDevices. That probably explains the difference between xinput --list and the debug output above. It does not explain why results between xinput1 and xinput2 functions differ.
