Bug Description

I cannot pair the Logitech K810 keyboard to my computer using the graphical interface provided by Ubuntu. Whenever I try I get two possibilities:

1. The GUI will show me a password, which I must type in the keyboard. After typing the password and pressing ENTER, the pairing will fail.

2. The GUI will hang for about a minute, and then fail to pair.

The only way I can successfully pair the keyboard is by looking at the output of hcidump -at while attempting pairing, and finding a line of output displaying the password that I must type, then typing that in the keyboard. The procedure I follow for successful pairing can be seen in this URL:

Previous comment contained an attempt to pair that failed. The GUI did not display a password to type on the keyboard, but the file registered one, as evidenced in this line:

2013-09-01 21:54:09.899971 > HCI Event: User Passkey Notification (0x3b) plen 10
    bdaddr 00:1F:20:*:*:* passkey 662178

If I had typed that passkey by looking at the contents of the dump while the GUI was attempting to pair, I would have been able to successfully complete the pairing.

Same problem with Logitech K760 on 12.10 & 13.04.

Also, I notice that the keyboard randomly looses its connection (sometimes in one day, sometimes a week, typically every 2-3 days). When this happens I have to manually delete the keyboard using the gnome-gui and repeat the steps outlined above and at: http://ubuntuforums.org/showthread.php?t=2101785.

In looking for a bug report I found a number of reports on different versions of Ubuntu. I suspect it has been here for a while and most people give up trying to use bluetooth for a keyboard.

This is reported against an old version of Ubuntu and many things has changed since then. Because of that we won't fix this issue however if this behavior repeats on a modern version please fill a bug report against it and we will take it from there.
