I found this: http://www.opensource.apple.com/source/IOHIDFamily/IOHIDFamily-258.1/IOHIDFamily/AppleHIDUsageTables.h which labels it as "Reserved MouseData" and it seems to be related to the capacitance detectors. Run "hcidump -X" and place your fingers on the mouse top without actually clicking then move the mouse slightly. You will see 0x00 (no touching), 0x01 (left finger), 0x02 (right finger) and 0x03 (both fingers). I didn't see any other values. I think the battery strength is found by polling with the feature report id#71 but I don't know how you do that, libusb might be able to do it? as I mentioned before, you will also get an input report id#42 sent before the mouse dies (but that is not listed in the HID descriptor) iain -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
