[Aspire S7-392] Touchpad reported as: "elantech: unknown hardware version, aborting"

[clayton craft]

Only basic functionality (right/left click, moving pointer) work. Expectation is that the device would be detected as a touchpad with support for multitouch/scrolling/etc. The laptop is an Acer S7 392. Please let me know if I can provide more information to help!

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 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'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Joseph Salisbury (jsalisbury)]

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.

[clayton craft (craftyguy)]

I have reported the bug to my best guess for maintainers ( <email address hidden>), and as of right now I have not heard back yet.

[kendatsuba (kendatsuba)]

Unfortunately, even if the driver complains of an unknown hardware version, the firmware version of the touchpad is not mentioned in the emitted error message:

[ 18.453420] psmouse serio1: elantech: unknown hardware version, aborting...

The module contained in the attached dkms package should print the firmware version along with the error message. By knowing the firmware version, it will be possible to force the recognition of the touchpad and see if the structure of the packets is the same used by one of the already supported firmwares.

Here are the steps you must follow:

sudo dkms ldtarball psmouse-elantech-show-version.tar.gz
sudo dkms install -m psmouse -v elantech-show-version

sudo rmmod psmouse
sudo modprobe psmouse

and post the output of the following command:

dmesg | grep elantech

When you're done don't forget to remove the module:

sudo dkms remove -m psmouse -v elantech-show-version --all

[clayton craft (craftyguy)]

Here's the output after building/loading that module:

clayton@ultrabook:~/Downloads$ dmesg|grep elantech

[clayton craft (craftyguy)]

I've made some (hopefully) interesting progress:

The firmware version seems to be 8, using the formula in the elantech_set_properties function, so I modified the file like this to force it to set hw_version to 4:

craftyguy, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (2.05). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.

[clayton craft (craftyguy)]

I would love to be able to update my BIOS, however Acer's flash tool only supports Windows. The BIOS appears to be based on Insyde EFI, and I was able to extract a .fd file, however I wasn't able to find a utility to actually flash it (from freedos or ??). Do you, or anyone here, know of a way to update this?

[kendatsuba (kendatsuba)]

Maybe I'm wrong but I don't think that a BIOS update will change anything, since this problem appears to be related to a new firmware version not yet supported by the driver.

craftguy, could you please report if your patch solved the problem? does the touchpad work as expected with hw_version = 4? In that case we can forward the patch to the subsystem maintainers.

[clayton craft (craftyguy)]

I did, here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1232877/comments/9

As far as I can tell, everything seems to be working properly

[penalvch (penalvch)]

kendatsuba, regarding your comments :
>"Maybe I'm wrong but I don't think that a BIOS update will change anything, since this problem appears to be related to a new firmware version not yet supported by the driver."

As you may have noticed in https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette , one would not want to presume what a BIOS update will or won't change, as they are a black box generally not tested to linux, and specifically Ubuntu. As well, hardware maintainers have already made clear bugs reported with outdated and/or buggy BIOS would need to be updated first before considered valid.

[Matthew Walker (matt-g-d-walker)]

Here is a I made patch that fixes this. I have submitted it upstream. A BIOS update is unnessesary. I have tested it and it works, I would appreciate other people trying it though.

[clayton craft (craftyguy)]

Unfortunately I killed my system when trying to apply a BIOS update to check another bug I reported, so I'm not able to confirm your patch (though I don't see any reason why that patch wouldn't work..)

[Joseph Salisbury (jsalisbury)]

Thanks for submitting the patch upstream, Matthew. Did you submit the patch to LKML or one of the sub-system mailing lists? It would be great if you could post the SHA1 for the commit when it is accepted into mainline. Trusty will pickup the patch when it is rebased to upstream. Saucy and other earlier releases would get your patch from the stable updates if you cc'd the patch to <email address hidden>.

[Daniel (skorka-b)]

Same isssue on an Sony SVF13N1L2ES, bios R0220VA. Standard kernel for 13.10 (3.11.0-14-generic) and latest mainline kernel (3.13.0-031300rc5-generic) say:
psmouse serio1: elantech: unknown hardware version, aborting...

Using module from comment #7 gives:
psmouse serio1: elantech: unknown hardware version 0x595f02, aborting...

which works out to version 9 in the drivers logic.
I did not try forcing recognition as hardware version 4, as I'm a little worried of inflicting damage.

[penalvch (penalvch)]

Daniel, thank you for your comment. So your hardware may be tracked, could you please file a new report by executing the following in a terminal while booted into a Ubuntu repository kernel (not a mainline one) via:

hello,

i have same issue with multi-touch elantech touchpad. hardware unrecognized
i have used the show-version module to check it up but im not sure how to read what hardware version is
any help please?

I have a system that matches the original reporter's system except for the machine's manufacturer that in my case is ASUS, for the Elantech's complete hardware string that in my case is 0x381f00, and for the kernel version that in my case is 3.11.0-22-generic.

I confirm that Matthew Walker's patch in comment #15 works fine.
