Intuos4 WL is separately reporting power supply and battery charging status - now hid-wacom is using that information. Previously hid-wacom was wrongly treating "battery charging" bit as "power supply connected". Now it should report battery charging, battery discharging, battery full and power supply status. Intuos4 WL sends reports when is in use (obvious) and when unplugging power supply. If means that if the device is being charged, but it's not being used it will never report "battery full". The same problem happens after the device has been connected, but it's not in use - the battery/ac status will be incorrect. Currently there is no mechanism to ask the device to send a report containing battery/ac status.
