Ubuntu 15.04 Bluetooth issues on a Macbook Pro Early 2015 (12,1)

[mj0g]

Quick update: I just tested linux 4.4-rc2 from the Ubuntu mainline kernel PPA and Bluetooth seems working fine on my MBP 12,1. Apparently Xenial will be based on 4.4, so the next release should support Bluetooth out of the box.

I can confirm that bluetooth (and everything else I've tried ) works fine withlinux 4.4-rc2.

Only problem: my bluetooth mouse (Microsoft Bluetooth Notebook Mouse 5000) is quite laggy, way more than the same mouse is on my old Dell XPS 13.
evhz from this page shows 350+ Hz polling rate, so that's not the problem.

Anybody else experiencing this?

Yeah, I get the same thing when using an Apple mouse.
