USB adapter will not connect in Ubuntu 15

Plugable USB-BT4LE, order 108-1693042-0644247.

I have a multi-boot set-up. Windows XP, Mint 17 Rebecca Mate, and Ubuntu 15.04.

Currently I am having trouble with Bluetooth on Mint and Ubuntu, but I want to tackle the bluetooth issue with Ubuntu.

Out of the box, this worked with Ubuntu. I had trouble with XP. Now that bluetooth work in XP, it does not work in Ubuntu.

Pairs, but does not connect. I can click connect but the Bluetooth headset option never appears in Sound settings and the connect switch does not move to ON.

I tried solution at:…
