Hi Martin, thank you very much for your answer. So this bug will be
fixed into 15.10 version: there is a way to try patched upowerd in my
15.04 or I must wait six months? I was curious to see if new upowerd can
detect right battery level: with current vesino my kernel says "WARNING
**: no valid voltage value found for device
/sys/devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3.2/1-3.2:1.0/bluetooth/hci0/hci0:11/0005:03F0:044C.0002/power_supply/hid-00:02:76:4f:9b
:cb-battery, assuming 10V" but it has only two AA battery so max level
is 2.8V

Bug description:
  I have a bluetooth Logitech M557, and it is being mis-detected by
  Upower as a battery instead of a mouse:

  The patch available in the upstream bug improves the situation by parsing it as a hid device, but then mistakes it for a keyboard:
