Comment 5 for bug 1369684

We found same issue on several devices (running Debian Whezzy with kernel 3.14)

But. we have many other "same" device with this firmware reported from psmouse:

[ 9.906882] psmouse serio4: elantech: assuming hardware version 3 (with firmware version 0x450f02)
[ 9.920408] psmouse serio4: elantech: Synaptics capabilities query result 0x09, 0x16, 0x09.

i down know if same touch hardware with different firmware or the hardware is no same

On the firmware 0x450f02 the problem does not happen

Do you have a bios update to try?

 I will contact to our vendor to ask if bios update can be fix the buggie devices.

on windows with 0x354f01 the issue is little different, the touchpad freeze few seconds and work again.
