Detailed report is here, basically can't get any event from the mouse:
https://superuser.com/questions/1697648/lenovo-legion-m600-wireless-bluetooth-mouse-connected-and-paired-yet-not-working

Have the same mouse and ready to provide any assistant to solve this. Any clue?

(If this is a tough problem I would probably have to return the mouse to store, it's not cheap..)

Hi Luiz, thanks for your response!
In btmon I see a lot of

events when I move the mouse.
Full log is attached in snoop and text formats.
Also I pressed all the buttons present on the mouse.

So we are receiving the reports:

So I suspect there is something in the HID/uHID not working then, what version of BlueZ are you using?

I try upgrading or better yet use the head since we have some fixes like:

Tried BlueZ 5.63 on my Fedora installation, no luck. Will try to build head if no better idea..

If that doesn't work I'm afraid you will need a dedicated kernel driver in order to deal with its HID reports since BlueZ just forwards the reports to the kernel.

That doesn't seem to work (meaning mouse doesn't move) .

Do you know where to get dedicated driver installation instructions?

Could you clarify do you mean usual BlueZ dedicated driver just built from bluetooth-next for my kernel or some non-existent driver one yet had to write?

In the latter case, do you have some sample drivers maybe one could easy to adopt?

Important addition: the mouse does work on Android 8.10.

Does it mean Android has that special HID driver that missed on Linux? 8.10 came out long before the mouse even existed..

Do you have explanation?

No, in fact android seems to also be using UHID, does it uses a vendor app to set it up?

No, it just works right away after connecting from Settings.

Also, the mouse works on Windows, without additional software. It's detected as "Bluetooth Low Energy GATT compliant HID device" there.

Did you manage to test with latest git? Note that windows does seem to handle composite HoG device:

Btw, it could be due to:

There were some systems (afaik 32bits) with a problem with the header copy we had.

Thanks, updated the issue with info. My device is probably composite indeed, as these ones:

https://github.com/kyokenn/rogdrv#rogdrv

I tried BlueZ master but userspace only.

My system is 64-bit. Do you think it's still worth to try to update BlueZ kernel part? If so, what is the procedure? Didn't find how to build BlueZ out-of-tree kernel modules or something..

https://github.com/bluez/bluez/issues/258

I built bluetooth kernel modules from bluetooth-next, tag v5.13. Not sure if it made any sense or my distro kernel already included them..

Anyway, there was no any difference in mouse behavior.

Oh, I built BlueZ from master so shouldn't be the case.

Can you please try using "hid-recorder" to capture the HID output out of the device? It would show us whether we're receiving any events from the device, and allow us to test whether there are problems at the HID level on other machines.

Cheers

It's a pity because the hardware itself is rather good, but I had only 14 days to decide.

Looks like there are others models affected as well:

https://github.com/bluez/bluez/issues/320

It is very weird that it would work with Android and doesn't with Linux since afaik the very same interface is used with uHID, are there anything on the kernel side we can switch on to see why reports would be discarded, because from the looks of it we do receive them but they just don't have any effect.
