Hi,

Just tested V1 again with both of the receiver versions I have on hand and the input issues I described happen on both.

I see. Then I assume it either comes down to our different keyboard models behaving differently, or something behaving differently in our setups. I use KDE Plasma on Fedora for what it's worth.


btw, thank you for pointing out that you can check the FW version in fwupd. This greatly simplified testing.

I do have one find -- when a device gets powered off (yanked battery, switch moved to the off position, switching devices), the battery stays in upower. Unifying also does this, disconnected devices stay. Either this was intentional or a bug. Either way the behavior is consistent with the existing code and isn't introduced by your changes. I'm just not sure what the correct behavior should be. Sorry if this pollutes the discussion, I'm completely new to the LKML.

Good find! I suggest we leave that separately though. But as I am also completely new to the LKML I don't know what best practices here are. Let's wait for maintainers to chime in :)


I'm not sure what else I could try, I'll keep your V2 on my system and let you know if any issues pop up.

Great, thank you!


Regards,
Kate

Hi,

Thank you very much for your help.

Unfortunately I don't have a Windows system easily accessible, so I
can't check my firmware version in Options+.
fwupdmgr says:
Current version:    MPR05.03_B0020
so perhaps that means 5.03.20.

Let me know if anything pops up if you dig some more,
Thanks,
Erik
