Magic Mouse Scrolling not working in Ubuntu 19.04

[ddalida]

I had this module working in 18.04 with the 4.20... kernel without issues. I know it has been implemented into the release but the scrolling isn't working. I've tried rmmod and insmod under the 5.0.0-13 kernel with 19.04 but no joy. This is with the Magic Mouse 2 and not the trackpad.

Am I missing something? Any info that could be relevant I can provide?

This is what gets loaded at startup (lsmod | grep hid):

@romanAbrahamovic how much work would supporting Magic Mouse 2 take? (Enabling scrolling, that is)

I recon there would be many Linux users happy to buy you a coffee if you got this working...

I found that there is a branch in @rohitpid's fork that is at least a start on getting MM2 to work, but I haven't tested it: https://github.com/rohitpid/Linux-Magic-Trackpad-2-Driver/tree/magicmouse2

[mrdev023]

It work i tested

[stubbulon5]

It work i tested

You mean Magi Mouse 2 scrolling with the above repository link?

I tested it today, and it worked! thanks @rohitpid

Hi, wondering if anyone can help with debugging an issue on this magicmouse2 driver. I'm using the fork from @rohitpid, unfortunately there's no way to file issues on that repo so I'm commenting here. The mouse connects over bluetooth successfully every time but the scroll wheel does not work until I reload the driver using:

sudo rmmod hid_magicmouse
sudo insmod /lib/modules/5.3.0-7625-generic/updates/dkms/hid-magicmouse.ko

These are the logs in ~/.local/share/xorg/Xorg.1.log:

I had the same issue and my mouse would randomly disconnect. I ended up getting rid of my magic mouse and switched to a logitech bluetooth mouse after I couldn't find a solution to the scrolling issue. You may have luck with the "unstable" branch mentioned above.

[RicardoEPRodrigues]

Hello, I have been scrolling through several of these issues and found some solutions, I decided to pick some of them up and compiled them. Can you please try my solution out?

https://github.com/RicardoEPRodrigues/Linux-Magic-Trackpad-2-Driver

This should fix 2 problems: Magic Mouse 2 driver not loading after reconnection and random Bluetooth disconnections.

[jeffywu]

@RicardoEPRodrigues, thanks! I tested out your instructions and they worked well. A couple minor suggestions. This udev configuration works well for me, in your version the second line is missing a comma and a backslash I believe.

SUBSYSTEMS=="input", \
    ATTRS{name}=="XXX", \
    ACTION=="add", \
    SYMLINK+="input/magicmouse", \
    RUN+="/opt/magic-mouse-fix/magic-mouse-2-add.sh"

I was able to view the properties on the mouse via dbus:
dbus-send --system --print-reply --type=method_call --dest=org.bluez / org.freedesktop.DBus.ObjectManager.GetManagedObjects

[RicardoEPRodrigues]

Hello, thank you for the input! I updated the udev rule. I hope it now works correctly:

SUBSYSTEMS=="usb", \
    ATTRS{idProduct}=="e300", \
    ACTION=="add", \
    SYMLINK+="input/magicmouse", \
    RUN+="/opt/magic-mouse-fix/magic-mouse-2-add.sh"

Correct me if I'm wrong, but I think this rule goes like: "if an usb device with the product id of e300 is detected (the ID is the one from the Magic Mouse) then load an input driver for that device".

I read more info on the device based on this command udevadm info -a -p $(udevadm info -q path -n /dev/input/eventXX). Change the /dev/input/eventXX with the correct device in your OS.

[RicardoEPRodrigues]

Hello again, sorry for the SPAM.

My solution doesn't work as is. The way I was trying to do things was to read an id from usb1/X-X which is specific to the PC and not the mouse.

I trying to find a solution. If we can find a Magic Mouse 2 ID in the udev info then we can change the rule and the solution should work for everyone.

If not, then I'm trying to find an ID in the Bluetooth info, with that we can have a script running every time an input device is plugged in, but that script will only load the drive if that device is a Magic Mouse 2.

You can help me by posting a file with the output of this command udevadm info -a -p $(udevadm info -q path -n /dev/input/eventXX), where you need to change the /dev/input/eventXX with the XX corresponding with the Magic Mouse 2.

[RicardoEPRodrigues]

Ok, I figured it out.

I rewrote the rule to catch all the Magic Mouse 2. FINALLY. Check this out:

SUBSYSTEM=="input", \
    KERNEL=="mouse*", \
    KERNELS=="0005:004C:0269*", \
    ACTION=="add", \
    SYMLINK+="input/magicmouse-%k", \
    RUN+="/opt/magic-mouse-fix/magic-mouse-2-add.sh"

Remember to try my ./install in my repo. Any input is good input.

[jeffywu]

The second rule works for me. Thanks for your effort!

This isn't working on Elementary OS 5.1.5. Here's the steps I'm taking. Move the original kernel driver hid-magicmouse.ko from my 5.3.0-59-generic kernel and running "depmod -a" then reboot. After the system comes back up I'm following the install instructions (git clone and then running the install.sh as root) and reboot. When the system is back up and I click the mouse it is seen and paired but the pointer doesn't move, the track-pad still works though. Here's the output from my xorg.log:
