I tested this in bug #1536669 on krillin and Unity 8 desktop on
Chromebook, and it worked fine with the example apps, the QML of which
called:
InputDeviceModel {
id: deviceModel
filter: InputInfo.Keyboard | InputInfo.Mouse | InputInfo.TouchScreen
onCountChanged: {
console.log("new count of filtered devices: " + devices)
}
}
It doesn't say it there but I believe I did test with my Bluetooth mouse
too. But maybe indeed there's some case either arale specific or related
to the mouse+keyboard combo.

Title:
Mir-backed InputDeviceModel doesn’t work on touch device
Status in qtsystems-opensource-src package in Ubuntu:
Confirmed
Bug description:
I’ve prepared a branch of webbrowser-app that makes use of the latest
qml-module-qtsysteminfo for input device detection
(https://code.launchpad.net/~osomon/webbrowser-app/use-
qtsystems/+merge/309667), and when I test it on arale, I’m seeing the
following error in the logs when connecting a bluetooth keyboard/mouse
combo to the device:
QObject: Cannot create children for a parent that is in a different thread.
(Parent is QInputInfoManagerMir(0xaa09a6ac), parent's thread is
QThread(0x1fba0b8), current thread is QThread(0xb08612d8)
This looks like a threading issue in the implementation of the Mir
backend for InputInfo.
