System hangs if apple magic mouse is connected via bluetooth

[JOnathanJOnes]

If you connect apple magic mouse via bluetooth the system hangs completely. After 1 minute the system restarts.

the workaround for turbo is to disable magic pad supporting.

And in Turbo, what caused rebooting is calling null function pointer hdev->hid_output_raw_report() [1]

Compare to Android behavior, that pointer is assigned in uhid module [2] , but Ubuntu touch did not go that way and just keep it NULL.

I also tried to skip calling hdev->hid_output_raw_report() then the magic mouse device could show in cat /proc/bus/input/devices [3] , but nothing show in evtest [4] and no mouse courser shown on device screen.

@alex, macgic mouse and magic trackpad are different. let's find a magic mouse to test.

It's confusing: On bq E5 works with no problem (apple magic mouse) even with bluetooth keboard at the same time.

On m10 if keyboard is connected, when tap on connect appel magic mouse, m10 freezes and reboots. If no keyboard is present, it does not connect. If mouse is clicked conmects briefly and disconnects inmediatly.

@koza - I think this should be handled as a dupe of all the other bugs relating to LE enabled devices.

i had the same experience with bq M10 and Microsoft Arc Touch mouse while pairing/connecting to bluetooth, unity 8 freezes/crashes

[dinamic (dinamic6661)]

on rc/proposed (ota14+)

Status changed to 'Confirmed' because the bug affects multiple users.

Reduced priority for Ubuntu Touch bugs.

[Daniel van Vugt (vanvugt)]

Ubuntu Touch is no longer supported.
