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
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.
** Attachment added: patch for drivers/input/mouse/elantech.c to allow
detection of newer elantech touchpads.
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..)

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
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.

craftyguy, as per http://us.acer.com/ac/en/US/content/drivers an update

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
I have reported the bug to my best guess for maintainers ( linux-
in...@vger.kernel.org), and as of right now I have not heard back yet.

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:

aborting...
The module contained in the attached dkms package should
Here's the output after building/loading that module:

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:
