I am using Magic Mouse 2 with ubuntu 20.04. To use the scrolling feature, I had to install this driver: https://github.com/rohitpid/Linux-Magic-Trackpad-2-Driver. The only problem is that I need to execute these two lines every time I restart or reconnect the mouse via bluetooth:
echo "0005:004C:0269.0008" > /sys/bus/hid/drivers/magicmouse/unbind
echo "0005:004C:0269.0008" > /sys/bus/hid/drivers/magicmouse/bind
If I did not unbind then bind after the mouse is connected, I could still use the magic mouse but the scrolling won't work.
Anyways, I was looking for a way to automate this whenever the mouse is connected via bluetooth. I found out about udev but could not get it to work without getting into infinite loop. Here is the content of my hid-magicmouse.rules file under /etc/udev/rules.d:
ACTION=="bind", KERNEL=="0005:004C:0269.*", SUBSYSTEM=="hid", DRIVER=="magicmouse", \
RUN+="/bin/bash -c 'echo $kernel > /sys/bus/hid/drivers/magicmouse/unbind'", \
RUN+="/bin/bash -c 'echo $kernel > /sys/bus/hid/drivers/magicmouse/bind'"
This gets into an infinite loop because the script will call itself again after executing the second line (bind command) which is the triggering action for this rule.
I tried changing the triggering action to "add" instead of "bind", but scrolling still does not work.
Here is the output of my udevadm monitor when the magic mouse is connected:

Any help to automate or fix this is appreciated!
