lsusb shows it:

 Bus 001 Device 005: ID 046d:c52b Logitech, Inc. Unifying Receiver

I have a M325 mouse and a K360 keyboard that have become unreliable so I've set out to re-pair but solaar does not see the receiver.

I've tried two receivers in different ports on the machine.

After heynnema's comment:

 solaar/eoan,eoan,now 1.0.1

There are no logitech or solaar files in /etc/udev/rules.d/ and no reference to logitech in any of the files in the udev directory.

I have run fwupdmgr -v update without any notification.

fwupd is already the newest version (1.2.10-1ubuntu2)

And the service is running.

However when I run

sudo fwupdmgr get-updates

1. Install the latest solaar

sudo add-apt-repository ppa:solaar-unifying/stable

sudo apt-get update

sudo apt-get install solaar # if Gnome then also install solaar-gnome3 (not required with recent versions of Solaar).

2. Check for udev rule

Check /etc/udev/rules.d for a file, called either 42-logitech-unify-permissions.rules or 60-solaar.rules.

3. Update the receiver firmware

https://support.logi.com/hc/en-us/community/posts/360033207154-Logitech-Unifying-Receiver-Update

https://support.logi.com/hc/en-us/articles/360035037273

Note: The Ubuntu Software app should be able to update the firmware also.

4. Check for plugdev group

groups

Make sure you're in the plugdev group

Note: log out/log in required if you added yourself to this group.

5. Replug

Unplug, and reinsert the receiver dongle.

Note: for debugging purposes, you can use the solaar show or solaar -d commands.

Note: see https://github.com/pwr-Solaar/Solaar for more info

Note: see https://github.com/pwr-Solaar/Solaar/tree/master/rules.d for udev rule installation

Note: see https://pwr-solaar.github.io/Solaar/installation for manual install instructions that might help debug

  • All checked and installed. NOTE: I am running MATE. Installing solaar-gnome3 will overwrite the MATE desktop settings and set up for gnome3 desktop. Not at all what I want. Been there/ Done that/ Won't ever do it again. Note that I found no logitech or solaar in /udev – Stephen Boston Jan 04 '20 at 15:47
  • @StephenBoston You might articulate your MATE environment in your question. Also, do you have a nano receiver, or a unifying receiver? In your BIOS, is USB set to legacy? – heynnema Jan 04 '20 at 15:59
  • @StephenBoston See https://github.com/pwr-Solaar/Solaar/tree/master/rules.d for udev rule. – heynnema Jan 04 '20 at 16:04
  • @StephenBoston see https://pwr-solaar.github.io/Solaar/installation for manual install instructions that might help you debug – heynnema Jan 04 '20 at 16:10
  • @StephenBoston status please... – heynnema Jan 09 '20 at 22:40
  • I have a new Logitech mouse and old keyboard, Solaar sees only the old receiver, and I can connect mouse only to the new receiver. The effect is that I have to waste 2 usb sockets
  • After installing the above Solaar from ppa:solaar-unifying/stable, it freezes on Ubuntu 20 (complains about missing udev fs)

  • @iirekm What version Solaar? Did you check #2 and #3 in my answer? Is the new USB dongle a unifying type (has orange symbol on it)? – heynnema Jan 04 '21 at 14:29
