synaptics touchpad. reconnect not supported

[Nicolò Chieffo]

I have a laptop that has a problem with the touchpad: if hitting a key
combination the synaptics touchpad loses the synchronization and it
reconnects.
this is the log output in kern.log:

The windows driver is smarter, and can handle device disconnections,
while the synaptics xorg driver (I have version 0.14.6) once the
device is disconnected, it treats it as a normal mouse after the
reconnection (no scroll, different acceleration, no finger
combinations,...)
