Elo TouchSystems touchscreen support? (04e7:0022)

Elo TouchSystems touchscreen support? (04e7:0022)

[Bastien Nocera]

[-- Attachment #1: Type: text/plain, Size: 476 bytes --]

Heya,

Built into my Lenovo A700 all-in-one is a touchscreen. lsusb says:
$ lsusb | grep -i touch
Bus 002 Device 006: ID 04e7:0022 Elo TouchSystems 

The touchscreen "works", in that tapping it will create a click event,
though that click event is always in the top left of the screen.

Full output of lsusb -vvv attached.

Anybody with ideas as to what I'm missing, or whether that particular
device is supported?

Using kernel 2.6.38-rc2-git5 (from Fedora rawhide).

Cheers

I take it this is a dual-touch device?

This is quite common for HID multitouch devices without proper driver
support. Sometimes using the HID_MULTI_INPUT quirk helps. Check
usbhid/hid-quirks.c for examples.

You probably noted already that the 04e7:0020 device is listed in
usbhid. Unless the device claims to be win7 compliant (implying
patching up hid-multitouch), going with the evtouch X driver might get
you a bit on the way. Or - god forbid - the binary blob drivers...

The serial elo driver has not been updated since 2007...

Henrik

To know if the device is "win7 compliant" or not, we need the full
output of lsusb (with the report descriptors).
You need to tell usbhid to release the device before calling lsusb -v.

Please use the script at
http://lii-enac.fr/en/architecture/linux-input/report.py
and run, as root: python report.py > descriptors.txt

This will do the job. You can then send us the descriptors.txt, and we
will see what we can do.

If your device is "win7 compliant" you will have to recompile a new kernel.

Cheers,
Benjamin

Attached (with the rest of the input devices stripped).

That's alright, I've done this before ;)

Hi Bastian,

well, apparently your device should be supported by hid-multitouch.

We will have to do this in two passes:
1) we enable it with hid-multitouch to be able to understand the protocol.
2) we tune the driver in order not making useless operations in the kernel.


First pass:
- please get the branch multitouch of jiri's tree (at
http://git.kernel.org/?p=linux/kernel/git/jikos/hid.git;a=shortlog;h=refs/heads/multitouch)
- then apply the attached patch (git am
0001-hid-multitouch-Introduce-Elo-TouchSystems-2515-Intel.patch)
- get your config from your current kernel (check that hid-multitouch
is enabled as a module)
- compile, install, reboot
- Now your device should still work and must be handled by hid-multitouch
if it's the case:
- mount -t debugfs none /sys/kernel/debug
- tail -f -n0 /sys/kernel/debug/hid/0003:04e7:0022:*/events | tee
logs_04e7_0022.txt

do one finger move on the screen, release
do 2 fingers move on the screen, release the first finger, then the second.

hit Ctrl-C in the terminal (lots of debug info should have been printed).

And send me the logs_04e7_0022.txt to got to the second pass.

Thanks,
Benjamin

That's where I hit a problem. It seems that the kernel on which that
branch is based has broken cgroups support (it panics on startup).

Would your patch, or a patchset be available to apply to the close to
Linus tree Fedora rawhide kernel?

As soon as I manage to get it to boot, I'll be doing that :)

Hi Bastien,

Sorry for that. Attached a new version that bumps a Linus' 2.6.38-rc2
or 2.6.38-rc3 to Jiri's tree and applies the patch above.

If it's still not working, I'll send you the files directly ;)

oops... When you say "the PCI ID seems to be in upper-case", you means
the path of the events file, or you had to modify the patch?

Is this the same with a Windows system? I don't think we made any
assumption on the pressure.

This is quite normal: Linux is not ready for multitouch right now ;)
Only the kernel is ready. People are working on x.org' XInput 2.1 to
enable multitouch in X.org, and the toolkits are following this
development.

If you want to give a try, you can download our mt-diagnostic software
at:  http://lii-enac.fr/en/architecture/linux-input/mtdiag.html .

Well, the device does not sends much relevant informations: we have to
rebuild some informations, so the final patch will be really close to
the one I sent last week. Once I made it, I'll ask you to test it
before submitting it for 2.6.38 (if it's still possible).

Cheers,
Benjamin

The sysfs path needed upper-case, yes. I did not change the patch.

I have no idea. I booted Windows once on this machine, when I actually
got it. I can certainly check there though.

That's alright. I know of the efforts, I stupidly thought that this
would behave the same way as the MacBook touchpads (eg. give me access
to a right-click).

Sure thing. I'll look for it in my mail.

Still interested in me trying out Windows for that "need to press hard"
touch?

You won't have the right click out of the box for now. Peter Hutterer
submitted last week patches to enable right click simulation with long
press. It works well for absolute device, but you need a development
tree of Xorg... So, we will have to wait for it too. :(

Sure, but I don't know if we will be able to solve it (I did not found
anything in the reports descriptors that add such feature).

Hi Bastien,

Can you give a try to the attached patch (it goes on top of the previous patch).
It would be great if you could play a little with mtdiag (or any other
multitouch application) and tell me if there is any problem.

Thanks,
Benjamin

The patch to work well, at least for touches with a single finger. I
launched mtdiag, but I have absolutely no idea what to test with it.

Hints?

Hi,

If you run mtdiag as root, your multitouch panel should appear with a
button "activate".
Click on activate, and it will show up a canvas in which the different
touch you made on the panel will be represented by a circle. The
bigger circle represents the mouse emulation of the device.

Cheers,
Benjamin

I finally took the time to build and test those patches you sent me, on
top of the Fedora 15 kernel, and they work great. When in fullscreen,
mtdiag works as expected though the roughness of touch is probably
because my screen is dirty as hell :)

Could you please get those pushed upstream?

Thanks for the work.

Cheers

Great. (not your dirty screen of course ;-D )

Good good, looks like there is a digitizer in there, with tipswitch,
inrange, contactid, x, y and contactcount. Paching up hid-multitouch
(and adding the device to the hid-core special device list) might
actually do it.
