** Description changed: - If I connect my magic touchpad after Unity has launched - in this case, - by clicking on it to wake it up and re-pair it with the desktop - then - it works fine as a touchpad but Unity fails to receive multitouch - (three-finger move, four finger swipe/tap) gestures. Restarting Unity - gets those gestures back. + SRU Justification + ================= + [Impact] + Without this fix, new multitouch devices connected to a computer after the user has logged in will not be recognized. They will continue to work as normal pointing devices, but they will fail to work for gesture handling. + + [Test Case] + Obtain a detachable multitouch device, such as an Apple Magic Trackpad. Leave it disconnected at first. Log in to Unity. Connect the device. Attempt to perform a gesture, such as a four touch tap to open the dash. The gesture should work. + + [Regression Potential] + Small. The code change is fairly trivial and should not cause any regression. Any regression that may be seen would involve devices not generating gestures due to mismatched gesture subscriptions. If gestures continue to work for all devices, then there is likely no regression. + + Original Bug Report + =================== + If I connect my magic touchpad after Unity has launched - in this case, by clicking on it to wake it up and re-pair it with the desktop - then it works fine as a touchpad but Unity fails to receive multitouch (three-finger move, four finger swipe/tap) gestures.
