EZBook 3 Pro Touchpad not working

Hello everyone. I'v bought a Jumper EZbook 3 Pro few days ago. First thing i did was to install Arch. Most of things work well out of box (apart from few odd issues), but the thing I can't get to work is a touchpad. I don't really know how to diagnose it.
I've tried to reload i2c module but that doesn't change nothing.

dmsg | grep i2c

Thanks for reply ibart. My problem is different. Could have mention it before. Touchpad works in Windows 10 and live Ubuntu + response.sh. It just won't work in Arch Xorg.

Re: EZBook 3 Pro Touchpad not working

Anybody still experiencing this problem? I'm having the same issue with my Chuwi LapBook Air - mouse completely dead.
I encourage possibly more people log it at https://bugzilla.kernel.org/show_bug.cgi?id=198627 as it hopefully the devs should be able to workaround this mousepad quirk.

Re: EZBook 3 Pro Touchpad not working

For those still struggling here, on my Chuwi LapBook Air, I have managed to "force" the touchpad to start working....eventually.

My setup and method, which I have managed to repeat after reboot to get the mouse working is as below.

1. Blacklist the driver and set debug options - (May not be necessary, but when the mouse isn't working my laptop fails to suspend/resume properly, so I have it blacklisted)

echo "blacklist i2c_hid" >> /etc/modprobe.d/00_i2c_hid
echo "options i2c_hid debug=1" >> /etc/modprobe.d/00_i2c_hid

2. Set debug i2c_hid kernel boot parameter

systemd-boot
------
options ***other options blah blah blah*** i2c-hid.dyndbg=+p

3. Reboot machine
4. After login, run

sudo modprobe -vr i2c_hid
sudo modprove -vi i2c_hid
I like the verbose flag so I can see what's going on

I have to repeat step 4 multiple times, I also use

sudo libinput debug-events

so I can see when the touchpad actually kicks in.

Hope this helps somebody, it'll just have to do for now.

EDIT: Scrap that, it's dead again
EDIT EDIT: seems to work if I

sudo modprobe -vr hid_generic
sudo modprobe -vi hid_generic

before removing/adding the i2c driver

blacklist i2c_hid
options i2c_hid debug=1

berzerking@ectoone:~/kernel/linux-4.15.3/drivers/i2c/busses$ cat ts.sh
sudo modprobe -vr hid_generic
sudo modprobe -vi hid_generic
sudo modprobe -vr i2c_hid
sudo modprove -vi i2c_hid

Re: EZBook 3 Pro Touchpad not working

I did not get it working on Arch Linux, how would you install a Ubuntu Kernel package on Arch? It should be possible to create a package based on the same vanilla kernel with all its patches but I don't have the time to research that option right now. What I did was just switching to Ubuntu until this issue gets sorted out on the kernel.

Re: EZBook 3 Pro Touchpad not working

Unfortunately, this looks like a signal integrity issue. I often get this when my system works on full throttle. I wrapped aluminum foil around the touchpad cable, and glued it on top of the traces. This partially solved the issue for me.

Why this doesn't happen in Windows  is because Windows is smart enough to restart the driver if it detects errors.
