introduced support for Logitech unifying devices. However, with 0.9.19
their charge is shown as 0%:

This leads to confusing output in both gnome-power-statistics 
(https://launchpadlibrarian.net/129122895/power-settings-window.png) as well as 
indicators (https://launchpadlibrarian.net/129122931/indicators.png).

I think as a defensive action we should not add a "percentage" property
if we are unable to read the actual charge, i. e. if it is 0.

Ideally we'd fix reading the charge, of course.

That doesn't sound complicated to fix, though I'm not sure what's the best 
strategy in term of UPower handling of that case. Richard, do you have any 
hint, or you're comfortable enough to fix it?
I can test a patch if you don't have the hardware.

I'm now at a machine which has these devices attached. I can reproduce
the bug with 0.9.19, but interestingly with git head I don't see the
devices at all any more. There might be some regression in
http://cgit.freedesktop.org/upower/commit/?id=b1f12feb1fd45, did you or
Julien happen to try current master with such a device?

The udev rule seems to work somewhat; it attaches the property to the
USB HID device (not the input device); I assume that's intended?

The "invalid bitmask" might be related to
http://cgit.freedesktop.org/upower/commit/?id=35b0d25 ?

With git reset to commit 35b0d25 I basically get the same output as with
0.9.19, so the "invalid bitmask" still remains with 35b0d25.
