I have been trying on Kubuntu 13.04, 13.10 and now 14.04 - but always the same problem!
The mouse works with my android mobile phone.

I use Kubuntu 14.04 here now.
When I press the "connect" button on my mouse, I cannot find it using KDE Bluetooth manager, thow rfkill list tells me, it's not blocked.
So I do rfkill block bluetooth && rfkill unblock bluetooth. Now the bluetooth icon appears in de tray area. I press the "conect" button on the mouse, it appears in the list, and I can finish pairing. Now everything works for 1 or 2 minutes, until the mouse won't work anymore. The tray icon still says "connected". I can also see the laser sensor flashing.

I am sorry I have no idea how to show the kind of bluetooth chipset I have, and also don't know how to debug the connection.

Please help me ;)

    Please run dmesg before you connect your bluetooth device. Then connect your bluetooth device and rerun dmesg. Add the new output to your question. Wait until your device disconnects itself. Rerun dmesg - are there any extra tracing available? If so - again add this to your question. Please can you also paste.ubuntu.com the output of hcitool dev and hcitool scan - thanks. – fossfreedom Mar 24 '14 at 12:32
  • No dmesg when loosing connection. Also I can still see the laser working. – davidbaumann Mar 27 '14 at 9:42

I have tested the following Logitech mice over the last 2 years (This information might give you an idea on how to test the mouse yourself and solve the problem):

  • T620 Touch
  • Anywhere MX
  • M555B

And I can say the following:

  • T620 Touch - Everything works in Ubuntu. From side scrolling to both buttons. From zooming to double clicking. The distance is the best out of the 4. The only problem is that it does not have a middle button.

  • Anywhere MX - Excellent mouse. The side buttons, 2 middles buttons and fast scrolling make it the most used one I have. The horrible problem is that it uses the batteries at least 3x faster than any other AND the distance is horrible. Less than a meter. I had to send it back and change it for a new one. After about 4 months the problem started again.

  • M555B - Excellent mouse and I like fast scroll it has BUT here are the problems you might be facing:

    • Power problems. The first one I had, I used new batteries (Tested the batteries in the T620 before using them in the M555) and somehow it did not work correctly. A lot of stuttering or simply going off after about a minute. At first I thought it was the Bluetooth (A Kesington 2.0) but it was working great with my Samsung S4. I then tested the M555 with the Samsung S4. It did not work. So I send the mouse back saying it had a bluetooth issue. Got a new one about 2 months later.

    • Bluetooth issue. It might be a BT issue with the mouse as mentioned above or with the BT of the computer. Test the BT with a phone or another BT device to see which one is the problem.

What I would recommend is that you connect the M555 to a phone or tablet that has BT support. If it works correctly then you know the problem is in the BT of the computer. If it does not, then it is the actual mouse the problem.

If the problem happens to be the BT of the computer then you can check which version of BlueZ you have. If you are in 13.10 it should be the 4.101. In 14.04 I do not know (I hope it will be the 5.17 that appeared yesterday since it will give support to a motherboard I have).

I would suggest compiling the latest BlueZ version and testing it out. The latest at least makes my BT of the computer (Asus Z87 Pro) work.

With this I am saying that Logitech are not very good with all products. Some will have some weird problems others will not. Apart from this, all Bluetooth devices or not working 100% yet (The latest ones). In the case of the M555B for me, I needed to change to another one to fix the problem. Tested on 13.10 right now.

To test what in the world is going on in your case I would first recommend doing the following (Does not matter if you do it before or after connecting the mouse):

tail -f /var/log/syslog

This will constantly display what is happening to the system. So after doing that connect or disconnect the mouse and try to pair it. Repeat at least 2 or 3 times with the working intervals you mentioned (2 or 3 minutes of working time). After you have enough logged information about what happens between connecting and the 2/3 minutes of disconnection, post that on http://paste.ubuntu.com and link it in your question or in a comment. This way we can do a follow up on it.


This might be simplistic question but just in case:

does your phone connection to the mouse is active at the same time you pair the mouse to your desktop? If yes, disable your bluetooth connection to the phone, reconnect to your PC and test it.

There is a really nice guide for Bluetooth Setup.

I hope this will provide you direction toward resolution of your problem.

  • Phone Bluetooth is switched off totally. Also, there's no other bluetooth enabled device next to me. – davidbaumann Mar 23 '14 at 14:48
  • Changed the location. Worked for 5 minutes, but same after this time. – davidbaumann Mar 27 '14 at 9:41

Logitech indicates that this problem can be caused by low batteries or Radio frequency (RF) interference from more powerful devices, such as:

Wireless speakers
Computer power supplies
Cell phones
Garage door openers

Before reconnecting your mouse

Fix or rule out the potential problems listed above.

Insert fresh batteries into your mouse 

Turn your computer on.

Reconnecting your mouse

Turn your mouse on — slide the power switch on the bottom of the mouse to the right.

Press the Bluetooth connect button.

Hopefully you will now see it in the KDE Bluetooth Manager and can connect normally.

  • Batteries are fresh. I guess I will try it somewhere apart of my electro smog room ;) – davidbaumann Mar 24 '14 at 23:26
