Hi, So it looks like Elantech devices also suffer from issues when used over PS/2. They also appear to behave properly when used over SMBus. On many systems, these touchpads are not enumerated by ACPI, but they are actually correctly working (after a few fixes from this series). I have been working with an owner to automatically bind the touchpad from PS/2, but mentoring a new comer takes time. Anyway, right now, it looks like adding "echo elan_i2c 0x15 > /sys/bus/i2c/devices/i2c-N/new_device" (N being the SMBus adapter number) at boot works well enough to have the touchpad bound. Currently the trackstick needs to be manually added by an extra patch but the information should be provided through PS/2 when the rest of the series comes.
