Bug#622707: Fwd: [Bug 36302] touchpad losing sync: 2 instances of synaptics module loaded and wrongly detected as multitouch
Below is the response I got from the synaptics driver developer. He
believes it's a kernel issue and it should be reported there.
I will try to push this in that direction

kernel issue. From the drivers POV, the touchpad disappears and a different
device comes back. That device doesn't look like a touchpad though and hence
the driver doesn't activate on it.
If you look at the second half of the log, you'll see that evdev finds x/y
relative and a few buttons. Touchpads, if not initialized by the kernel,
usually look like PS/2 mice. Tapping and other features are implemented in
hardware/firmware and look like a button click once the event reaches user
space.
Please report this to the kernel, it needs to re-initialize the touchpad.
