Bug Description

Hello,
We have laptops with touchpad Hantick, that on Miscrosft Windows work with Elan driver.

Linux does not recognize the Hantick touchpad as a touchpad and does not enable all the functions of evdev or libinput.

Thanks

As I said at the beginning, the Miscrosoft Windows the Hantick touchpad is recognized as ELAN and works correctly.
Other linux users with other hardware recognized as ELAN, have more parameters available:

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.11 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Can you add "i2c-hid.dyndbg=+p" to your kernel parameter and attach full dmesg here?

Well, then you probably need to ask Hantick or Elan for their support.

Thanks @kaihengfeng
Neither Hantik nor Elan support Linux, we have already consulted with them.
We have the same computers with 2 different touchpad. We can assemble the orders with Cypress touchpad and Hantik touchpad (Synaptics does not manufacture in the correct size of these cases)

Your solution solved other bug opened, but partialy.
Can you read my last response?

Hello @kaihengfeng

To start I just need the hardware to be recognized as touchpad, so that in the control panel, in Mouse options, also appear on options of Touchpad.

Hardware Unique ID: AH6Q.bGO0sOimOM3

The touchpad works reasonably with libinput and with evdev, but it is recognized as a mouse and therefore not configurable by the user. The user can not activate options like "Natural Scrolling", Velocity, etc.

We have developed an application [1] that allows users to change parameters of libinput and evdev, to activate the natural scrolling. But the customers have to install it additionally.
The correct is that it recognizes that unique hardware like touchpad, which is what it really is, and thus Ubuntu allows to configure parameters without needing to install third-party applications.

That's why you need vendor support.

We assemble the pieces.
The touchpad manufacturer does not support Linux and refuses to give it.

I just need the hardware ID: AH6Q.bGO0sOimOM3 to be recognized as touchpad, it does not matter if it uses the protocol of libinput or evdev, because both protocols allow to configure the natural scrolling.
But Ubuntu says that this hardware is a mouse and does not display the option to activate the natural scrolling.
