Bug Description
Bluez 5.3 does not have support for pairing with devices (such as keyboards) that use a PIN code for pairing.
A mouse pairs correctly.
From my research it seems as if the ChromeOS project developed patches to fix this and they are supposed to have been included in Bluez 5.4 (that statement dated April 2013) but I've not yet identified them.

Along with the loss of Headset profiles meaning VoIP applications can no longer use HSP/HFP profiles (requiring functionality yet to land in Ofono) this cripples the use of Bluetooth for much else than A2DP or mouse input.
Attempting to pair with, for example, an Apple Wireless Keyboard that pairs and works correctly with 14.04 LTS, fails totally on 15.10.
The mouse shown below is already paired, connected, and working.

This cycle repeats in various permuations. Sometimes the final "Request PIN code" does not appear.
