Undetected Logitech MX 5500 Keyboard and Mouse

Solution 1:

That is part of a bug had been around for a while. Launchpad Bug 870227.

The only fix for now for 12.10 is to have a separate keyboard (or boot in to an OS that can modify your installation) and go in to /lib/udev/rules.d/97-bluetooth-hid2hci.rules and comment out these lines:

# Logitech devices
#KERNEL=="hiddev*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[345abce]|c71[34bc]", \
#RUN+="hid2hci --method=logitech-hid --devpath=%p"

Just put a # at the beginning like in the code above.

Solution 2:

This problem also occurs in 16.04 LTS.

The problem is that you can't enter the pin when trying to pair the keyboard/mouse in bluetooth settings.

Found this solution which works for my own MX 5500 Keyboard and mouse

On 15.10 Wily Werewolf though, the path to the modified file is:

/lib/udev/rules.d/97-hid2hci.rules

I modified line 14:

From:

KERNEL=="hiddev*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[345abce]|c71[3bc]",

To:

KERNEL=="hidraw*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[345abce]|c71[3bc]",

Thank you for sharing the solution :)
