Logitech MX Keys-keyboard identified as event-mouse (instead of event-kbd)

Support
1

Hi all

My MX Keys are identified as a mouse. And it’s driving me crazy :fire: :grinning_face_with_smiling_eyes: …

Introduction

Today I tried to start my KVM with Windows 10. The mouse was passed-through like it should, but my MX Keys keyboard didn’t pass-through as it should.

For a period of time, I thought my KVM-setup was broken, after a update, or so… But after some (well… all the way to much time) debugging, I spotted that my Logitech Unify-device has two keyboards paired. The old keyboard was listed in /dev/input/by-id, identified as my keyboard, but the new was not…

I removed both keyboards in Solaar, replugged the USB-device, paired my MX Keys, switched to linux kernel 5.10.63-1, and rebooted the machine. But the MX Keys was still mapped to /dev/input/by-id/usb-Logitech_USB_Receiver-if02-event-mouse…

Problem

My MX Keys are identified as a mouse, and mapped to /dev/input/by-id/usb-Logitech_USB_Receiver-if02-event-mouse (/dev/input/event13), instead of event-kdb or something like that.

After finding the right search-keywords, I spotted this thread.

I hope that someone are able to help with the following things:

  1. Please help me understand, what’s going on. It’s diving me crazy. I can’t really understand why a problem like this shows up - but maybe it’s related to the Logitech Unify-adapter driver, and the MX Keys keyboard?

  2. Help me fix the current problem on my machine. Get my MX Keys identified as a keyboard, instead of the event-mouse.

  3. If I can help with anything, to get this bug sorted out for other users too., I’m happy to help with more information (if needed). :smiley:

My old K800 are still being identified as it should, if I re-pair it.

Outputs of a few commands…

Extra scenario: MX Keys paired to the Logitech Unify-receiver, as the only device

If I remove all other devices than the MX Keys, that’s still identified as the usb-Logitech_USB_Receiver-if02-event-mouse…

So the problem are isolatd to the MX Keys. The combination of mulitple devices, doesn’t matter at all. I’ve updated the first post.

Note that I added the MX Master, after boot was done, and I’ve checked the mappings…

Logitech is one of the few major brands that totally ignores Linux and it’s up to the enthusiasts that have Logitech hardware to hack the Windows drivers and implement the same functionality in the Linux kernel, so if a piece of Logitech hardware doesn’t work on the latest stable kernel, replace it, you’ll never get it to work unless you become a kernel developer.

:sob:

Hi Fabby

Sad news… I don’t have the proper knowledge, to deep-dive into the kernel… But I would like to help out, if that matters.

Two things for sure:

  • I will keep my MX Keys, and make a work-around if (sadly) needed
  • If I can provide any kind of information, I’m willing to help. With that said, I must say it would surprise me, if the support for MX Keys won’t go into the kernel, in the future. The MX Keys are a popular product (as pr. my understanding)

:smiley: :slight_smile: :crying_cat_face:

  • Find the person who is doing this heroic task (I’m not a kernel dev neither)
  • send him the hardware
  • include 100$/€ cash
  • Include a thank you card

That gets you a lot of goodwill everywhere!
