Is there still something I can do to help with progress on solving this issue?
I'd really like to use my mouse without the USB cable...

Hi Szymon,

thanks a lot for your effort! I've applied your patch on top of kernel 5.1.11
and I can confirm the mouse is working now.

The only downside I've noticed so far is that the scroll wheel stopped working
after 1-2h of usage.

@Michael

the scroll wheel that stops working is not related to Bluetooth.
I experienced the very same issue with the scroll wheel when using the mouse
via USB. This happened since the upgrade to Ubuntu 19.04 and I think it is
related to the desktop environment. It seems to be sometimes triggered by lock
screen or suspend (but not 100% reproducible). Reconnecting the USB (or
reconnecting via bluetooth) lets the desktop re-initialize the mouse and
resolves the scroll wheel issue.

I've patched bluez according to your link and after some hours of usage I
couldn't reproduce the scroll wheel issue. So on my primary device (laptop)
everything works!

Unfortunately on my desktop system I've another issue, again this could be
entirely unrelated:

After applying the kernel patch (and in anticipation the bluez patch) on my
desktop system, the pairing process also went smoothly. 

The mouse is shown as paired and connected according to the KDE plasma UI
tools, but apparently the mouse is not detected by the input system.
Dmesg only shows warning added by the patch and not any of the following input
stuff (taken from my laptop):

What could I missing out?

Ok, I compared the kernel configs between the working and non-working systems,
it seems like the kernel config entry CONFIG_UHID (User-space I/O driver
support for HID subsystem) was missing.

Everything is running fine now. I hope both patches are picked up in their
following release.

Thanks again.

Kernel patch is merged into bluetooth-next and is on its way to linus tree. It
is also marked as stable candidate.

Mentioned scroll issue fix is now also merged into bluez tree.

I think this bug can be now closed.

Thank you Szymon!

A small question about when we can expect a new Bluez release. Last one is from
a year ago and it would be great to get all fixes of last year into Linux
distributions.

I am also wondering when can I get the fixes... I ave both issues, the mouse
