Device support: Logitech MX Anywhere 2

Created by: fropeter

This is not included on the device page, so I thought I'd submit some data: (see below for a power issue)

The mouse is rechargable as opposed to the model "MX Anywhere"

     Battery: 0%, recharging.

I wonder if this is an issue or normal behaviour: It seems that solaar only reports 90%, 50% or 20%. Even when the data above was collected, solaar shows 20% and a warning sign in the gui, not the 0% and charging state. As I'm writing this, the mouse has been charging for a while, but there is no change in the gui or cli. I don't think the 0% is correct either. EDIT: I just checked the charge again. With power unplugged 'solaar show' reports 50%, plugging in power results in it reporting 0%, recharging again. No change in gui; still 20% with a warning.
