N-trig DuoSense digitizer not detected on Fujitsu Lifebook T580 on Ubuntu 10.10, amd64

[Bayle Shanks]

SRU Justification
=================
[Impact]
Newer N-Trig touchscreens on devices such as the Fujitsu Lifebook T580 do not work.

[Development Fix]
The HID parser was invalidating a field from newer N-Trig devices due to a check of the HID report size. Bumping the maximum allowed HID report size resolves the issue. N-Trig may be using an invalid report size, or the check may be incorrect, but the fix is merely a lessening of a protocol check.

[Stable Fix]
Please see the three attached patches. The first two patches revert the device IDs to match what the upstream driver has. The upstream driver is technically incorrect in how it is constructed; it preemptively lists device IDs that are unknown. However, newer devices with previously unknown device IDs have appeared, and the patch we added to restrict device IDs is preventing them from working. The best approach here is to revert to how the upstream driver handles this, and then fix any further issues when they arise. It is worth noting that no one has mentioned issues with the upstream device ID list yet.

The third patch bumps the HID report size check. It is a cherry-pick from the upstream HID tree. It will be merged into Linux 3.4 and eventually come down as a stable patch through the upstream stable queue.

[Test Case]
Try to use the touchscreen.

[Regression Potential]
Minimal. This brings us more in sync with upstream, and upstream has not reported any issues with the N-Trig device IDs. The HID report size check is a protocol check; at most, it will allow non-conformant devices to continue to operate. It is highly unlikely this will lead to any issues.

Original Bug Report
===================
Binary package hint: utouch

USB entry is Bus 002 Device 004: ID 1b96:0008 N-Trig

"Ntrig" doesn't appear in /dev/input/by-id/usb-*

utouch is version 1.1.

modprobe hid-ntrig doesn't seem to help. "sudo add-apt-repository ppa:utouch-team/utouch; sudo aptitude install hid-ntrig-dkms" doesn't seem to help.

thanks for your help

Henrik, did you get Micki's list of additional product id's when you
forked hid-ntrig?

Bayle, please send the output of "modinfo hid-ntrig". Specifically I
would like to know if you see this line:

alias: hid:b0003v00001B96p00000008

Also more for my curiosity than this specific bug, Bayle would you mind
sending the output of "lsusb -v" and "dmesg | grep ntrig". I have not
seen the specs of the panel on the T580.

Thanks,
Rafi

i meant 11.04 (natty), not 11.4, sorry

[Henrik Rydberg (rydberg)]

Hi again, does this version work better? Thanks for testing!

[Bayle Shanks (bshanks)]

hi, right now i'm on 2.6.35-28 [maverick], lemme know if that's a problem

[this error does not occur when i install the "test1" package that you provided in attachment #4, only with the test5 package that you just sent]

thanks

[Henrik Rydberg (rydberg)]

My bad, I assumed this would be for natty now. Backporting to maverick will probably happen at some point, but it would be even better to get a confirmation that this works in natty.

[Bayle Shanks (bshanks)]

ok i tried it on 2.6.38, but it didnt work and i got this in the syslog:

Mar 23 00:10:00 bshanks kernel: [ 3.173909] ntrig 0003:1B96:0008.0001: hiddev0,hidraw0: USB HID v1.10 Device [N-trig DuoSense] on u

[Henrik Rydberg (rydberg)]

Interesting. This will turn on more information:

echo 1 | sudo tee /sys/module/hid/parameters/debug

(a zero will turn debug output off)

In addition, since it seems to be a parsing error, having the full description of the device would be useful. Please download this script, for instance like

wget http://lii-enac.fr/en/architecture/linux-input/report.py

And run, as root

python report.py > descriptors.txt

Attach the descriptors.txt file here. That should give the full picture.

Thanks!

[Bayle Shanks (bshanks)]

ok, on 2.6.38, i did roughly:

sudo dpkg -i hid-ntrig-dkms_1.1.3~test5_all.deb
echo 1 | sudo tee /sys/module/hid/parameters/debug
sudo modprobe hid-ntrig
tail /var/log/syslog

wget http://lii-enac.fr/en/architecture/linux-input/report.py
sudo python report.py > descriptors.txt

the relevant entries in the syslog tail are:

and descriptors.txt is attached. however, report.py reported an error:

[Henrik Rydberg (rydberg)]

Thank you very much for this information. It seems your device hits a limitation in the hid parser. The attached package changes that limitation, but might have other side effects. Once again, the debug output will be most valuable. Thanks!

The latest ntrig driver is 1.1.4, so perhaps you like to try again with a fully updated system.
Also, the hid-dkms package was updated for other reasons, so please try the new attached version. Thanks!

[Henrik Rydberg (rydberg)]

The hid-ntrig-dkms-1.1.3 version had mismatching package and installation version, very confusing. I have uploaded 1.1.5 to fix that. All current package do however compile and run as expected, so previous comments still apply. Thanks!

i should note that there was some difficulty installing hid-ntrig-dkms -- it complained that it couldn't find /usr/src/hid-ntrig-1.1.5.dkms.tar.gz. I did "sudo apt-get source hid-ntrig-dkms" and then manually moved the resulting hid-ntrig-dkms_1.1.5.tar.gz to /usr/src/hid-ntrig-1.1.5.dkms.tar.gz

[Henrik Rydberg (rydberg)]

Something else seems to be wrong here. I have never seen the package problem before, and it works fine in this end. Fully updated natty. I just do

sudo apt-get install hid-ntrig-dkms
reboot

to install, and

sudo apt-get purge hid-ntrig-dkms
reboot

to uninstall.

[Johan Bernhardsson (smallone)]

By adding a device id in hid-ntrig.c so it looks like this:

static const struct hid_device_id ntrig_devices[] = {
        NTRIG_DEVICE(0x0001),
        NTRIG_DEVICE(0x0006),
        NTRIG_DEVICE(0x0008),
        { }
};
MODULE_DEVICE_TABLE(hid, ntrig_devices);

that makes my computer show ntrig in dmesg :

Tested on several t580 ... and after changing some code it works

[kinta (kinta-communia)]

After installing the last two packages I can confirm that ntrig on xps 15 is working too. No multitouch at first sight.

[kinta (kinta-communia)]

Sorry, but multitouch is working, what's not working is pen. (xps 15 l502x with 11.04)

[cortes_ (sovmirich)]

Hi, I have Fujitsu t580... What do I need to install that would touchscreen. If you can describe the process steps. Or by mail sovmirich @ gmail.com. Thank you!

[adamovera (adamovera)]

I also have a Fujitsu LIFEBOOK T580. I tried two of the last 3 packages on Oneiric 32-bit. The first one labelled 1.1.2~utouch2-test gave off an installation error, but it shows up as installed. The next one labelled 1.1.5~test (this appears twice, so I'm assuming that's just a double post) installs fine. The touchscreen is still unresponsive. Am I missing any steps, something else? The last post from smallone says 'after changing some code it works' - what changes?

[Johan Bernhardsson (smallone)]

adamovera: the changes i did isnt in the ntrig driver in the kernel for onceric apparently.

By adding a device id in hid-ntrig.c ( i dont know what row atm) so it looks like this:

static const struct hid_device_id ntrig_devices[] = {
        NTRIG_DEVICE(0x0001),
        NTRIG_DEVICE(0x0006),
        NTRIG_DEVICE(0x0008),
        { }
};
MODULE_DEVICE_TABLE(hid, ntrig_devices);

And by changing report_size to 96 in hid-core.c did the trick in the driver here.

I havent done the same for onceric yet. Can someone push these changes upstream to the kernelteam ?

[Chase Douglas (chasedouglas)]

I have added the new ntrig device id to this package. I have not modified hid-core.c because I'm not sure exactly what needs to be changed and changing hid-core would require modifying another package. Please test this package out, and if it doesn't work please check dmesg for any error messages.

Thanks!

[tuxsurfer (thomas-bretthauer)]

Hi Chase,

installed the package on the T580 running oneiric ocelot, but touch and pen don't work.

[Johan Bernhardsson (smallone)]

Thats probably beacuse the hid-core cant handle the output from
hid-ntrig.

I will try tomorrow to build the hid-core package aswell

Johan, did you ever have any luck?

[Johan Bernhardsson (smallone)]

No time. But as bord hid-core and hid-ntrig is in the kernel. This
should be reported to the kernelteam with the patches contained in
here.

If i get some time i will send a patch to the kernel.org so it will be
in upstream later on.

I have build a new hid-dkms package that bumps the maximum hid item size from 32 to 96. This is merely a guess based on what was suggested in a previous comment, but it shouldn't be harmful if it's incorrect. Please install this alongside the hid-ntrig-dkms package and reboot to test.

Thanks!

[adamovera (adamovera)]

Chase,

Nice! Both pen and touch work in Oneiric now. I'll shoot you an email with any impressions/questions/concerns after I have some time to play around with it.

-Adam

[Chase Douglas (chasedouglas)]

Our kernel has differed with regard to the ntrig driver. We are investigating our options with how to proceed with it. It is possible that the upstream driver works properly without any patches. I would appreciate it if someone with this device could test out the latest upstream kernel at:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.1-oneiric/

Thanks!

[Johan Bernhardsson (smallone)]

@chasedouglas i did test the kernel. In that kernel there are the parse issue in the hid driver. Where you need to raise hid item size from 32 to 96.

The ntrig driver is detected correctly but fails to load due to that.

hi, i wanna say that also latitude xt3 digitizer doesn't work, but neither with these patches!

ciao Igor

[Monica Jae (monicajae)]

i want to also add that none of these patches helps me and i have a t580. i installed ubuntu via wubi. the reason for this is that my cdrom drive is not detected at startup. this was the only way to get ubuntu insatlled and in the boot menu.

my ntrig is not being detected at boot so it is neither being loaded. i cannot load hid-dkms due to an error that file is not found. i cannot either install compiz-utouch because i cannot find the abiversion. i would like some help with thses issues if someone can find me a direction. thanks
Monica
