Please add psmouse.dyndbg=+p to the bootargs, boot the kernel, then upload the dmesg.

After that, add psmouse.proto=bare to the booargs, boot the kernel test if the touchpad can work or not.

Hi Hui Wang,

Thanks for the quick reply. I'm new to this place and i believe changes has to be done in "/etc/default/grub"

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash psmouse.dyndbg=+p"

One observation after boot-up;

dmesg | grep "i2c_hid"
[ 3.016774] i2c_hid i2c-SYNA3602:00: i2c-SYNA3602:00 supply vdd not found, using dummy regulator
[ 3.016799] i2c_hid i2c-SYNA3602:00: Linked as a consumer to regulator.0

Attached latest dmesg.

Added psmouse.proto=bare to "/etc/default/grub" and rebooted.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash psmouse.dyndbg=+p psmouse.proto=bare"

Still not working.

Oh, your touchpad is i2c-hid, so it has nothing to do with psmouse.

Please add "i2c-hid.debug=1" and "hid.debug=1" to the bootargs, then upload the dmesg.

Please check the latest dmesg.

Please test this kernel:

Use the descriptor in i2c-hid-dmi-quirks.c.

Hi Kai-Heng Feng,

The patch is working fine. Thank you so much. The touchpad now lists in xinput,

When will this patch gets integrated to main stream kernel?

Thank you.

We may have found a real fix to the issue.

Hi Kai-Heng Feng,

I have a laptop with the same problem. It's a SCHNEIDER SCL142ALM.

I have compiled the ubuntu kernel modifying the "i2c_hid_dmi_desc_override_table" to add:
  .ident = "SCHNEIDER SCL142ALM",
  .matches = {
  .driver_data = (void *)&sipodev_desc

And it's working fine.

Probably I could ask to include it in the next kernel version, but I think that it's not a good option to modify the kernel for every new vendor and model that decides to use this device.

It would be possible to add some parameter in the bootargs like for example psmouse.proto=sipodev and then use the i2c-hid-dmi-quirks?

In the meanwhile, please can you add the SCHNEIDER SCL142ALM to the override list?

Than you.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-disco' to 'verification-done-disco'. If the problem still exists, change the tag 'verification-needed-disco' to 'verification-failed-disco'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See for documentation how to enable and use -proposed. Thank you!

    pinctrl: intel: Clear interrupt status in mask/unmask callback

    Commit a939bb57cd47 ("pinctrl: intel: implement gpio_irq_enable") was
    added because clearing interrupt status bit is required to avoid
    unexpected behavior.

    Turns out the unmask callback also needs the fix, which can solve weird
    IRQ triggering issues on I2C touchpad ELAN1200.
