[Lenovo Miix] Synaptic/ITE Tech touchpad (06cb:a001) cannot be configured by hid-rmi

[Nicolas]

Problem:
The touchpad in the dock of the Lenovo Miix 2 11 tablet does not work. It is handled by hid-rmi, which fails to configure the device:

The Keyboard (which works) and the touchpad are connected as one USB device with two interfaces:

Workaround:
The touchpad works with hid-generic, if it is forces to handle the device. Yet, multitouch and dragging does not work.

[Brad Figg (brad-figg)]

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1437759

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Philipp Spilger (philipp-spilger-deactivatedaccount)]

I'm experiencing the same problem as you, but how exactly were you able to force hid-generic to handle the device, because simply blacklisting hid-rmi results in the device not being recognized at all with my machine.
Thanks in advance for your time.

[Nicolas (niccer)]

To force hid-generic, remove hid-rmi, load hid-generic and run:

echo echo 3 06cb a001 0 | sudo tee /sys/module/hid_generic/drivers/hid\:hid-generic/new_id

By the way, the touchpad has a Synaptics S3203B chip.

[Joseph Salisbury (jsalisbury)]

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 v4.0 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.

[Philipp Spilger (philipp-spilger-deactivatedaccount)]

I just tested the latest upstream kernel and the problem still exists. (with the same error message).

In my case, the issue was never resolved (with no older version). I only got both the keyboard and the touchpad working with debian wheezy (kernel version 3.2.0), but the kernel module hid-rmi is not available in this version, so i assume (did not check for multitouch, etc.) the workaround, as described on top, was applied automatically in this kernel version.

[Mark Roduner (mroduner)]

Okay, so I managed to come up with a workaround(ish) thing for this particular problem; you need to reload the hid-multitouch kernel module, and then re-enable the device using xinput.

Example script

#!/bin/bash
# Touchpad / Touchscreen Fix Script
# 2016.05.24
# Mark C. Roduner, Jr.

# If Run as root; fix all users, otherwise fix the current user

SCRIPT=$0

#Space separated list of kernel modules to reload
MODS_RELOAD="hid-multitouch"

get_users() {
        #echo ":1 mroduner"
        w -sh | sed -r "s/([^ ]+)[^:]+(:[0-9.]+).*/\2 \1/" | sort | uniq
}

execute_fix() {
        export DISPLAY="$1"
        sudo -iu "$2" $SCRIPT
}

get_core_regex() {
        xinput --list --long | grep "Virtual core" | sed -r 's/.*id\=([0-9]+).*/\\b\1\\b/' | sort | uniq | tr '\n' '|'
}

get_all_pointers() {
        xinput --list --long | grep XIButtonClass | sed -r "s/.*: ([0-9]+).*/\1/" | sort | uniq | tr '\n' ' '
}

get_real_pointers() {
        EXPR="`get_core_regex` +"
        get_all_pointers | sed -r "s/$EXPR/ /g"
}

if [ `id -u` -ne 0 ]; then
        echo "Enabling devices for ${USERNAME}${DISPLAY}... "
        for PTR in `get_real_pointers`; do
                xinput set-prop $PTR "Device Enabled" 1
        done
        exit 0
fi

echo -n Reloading Modules:
for MOD in $MODS_RELOAD; do
        echo -n " $MOD"
        rmmod "$MOD" && modprobe "$MOD"
done

echo -e "\nFixing Input Devices..."
CDISP="$DISPLAY"
get_users \
| while read USER; do
         execute_fix $USER;
done
export DISPLAY="$CDISP"
echo -e "\nDone."
