In the HID++ 2.0 function getBatteryInfo() from the BatteryVoltage
(0x1001) feature, chargeStatus is only valid if extPower is active.
Previously we were ignoring extPower, which resulted in wrong values.
Example:
With an unplugged mouse
$ cat /sys/class/power_supply/hidpp_battery_0/status
Charging
This patch fixes that, it also renames charge_sts to flags as
charge_sts can be confused with chargeStatus from the spec.
Spec:
+--------+-------------------------------------------------------------------------+
| byte | 2 |
+--------+--------------+------------+------------+----------+----------+----------+
| bit | 0..2 | 3 | 4 | 5 | 6 | 7 |
+--------+--------------+------------+------------+----------+----------+----------+
| buffer | chargeStatus | fastCharge | slowCharge | critical | (unused) | extPower |
+--------+--------------+------------+------------+----------+----------+----------+
Table 1 - battery voltage (0x1001), getBatteryInfo() (ASE 0), 3rd byte
+-------+--------------------------------------+
| value | meaning |
+-------+--------------------------------------+
| 0 | Charging |
+-------+--------------------------------------+
| 1 | End of charge (100% charged) |
+-------+--------------------------------------+
| 2 | Charge stopped (any "normal" reason) |
+-------+--------------------------------------+
| 7 | Hardware error |
+-------+--------------------------------------+

/*
|
|
* There are two hidpp protocols in use, the first version hidpp10 is known
|
|
* as register access protocol or RAP, the second version hidpp20 is known as
|
|
* feature access protocol or FAP
|
|
*
|
|
* Most older devices (including the Unifying usb receiver) use the RAP protocol
|
|
* where as most newer devices use the FAP protocol. Both protocols are
|
|
* compatible with the underlying transport, which could be usb, Unifiying, or
|
|
* bluetooth. The message lengths are defined by the hid vendor specific report
|
|
* descriptor for the HIDPP_SHORT report type (total message lenth 7 bytes) and
|
|
* the HIDPP_LONG report type (total message length 20 bytes)
|
|
*
|
|
* The RAP protocol uses both report types, whereas the FAP only uses HIDPP_LONG
|
|
* messages. The Unifying receiver itself responds to RAP messages (device index
|
|
* is 0xFF for the receiver), and all messages (short or long) with a device
|
|
* index between 1 and 6 are passed untouched to the corresponding paired
|
|
* Unifying device.
|
|
*
|
|
* The paired device can be RAP or FAP, it will receive the message untouched
|
|
* from the Unifiying receiver.

* Logitech M560 protocol overview
|
|
*
|
|
* The Logitech M560 mouse, is designed for windows 8. When the middle and/or
|
|
* the sides buttons are pressed, it sends some keyboard keys events
|
|
* instead of buttons ones.
|
|
* To complicate things further, the middle button keys sequence
|
|
* is different from the odd press and the even press.
|
|
*
|
|
* forward button -> Super_R
|
|
* backward button -> Super_L+'d' (press only)
|
|
* middle button -> 1st time: Alt_L+SuperL+XF86TouchpadOff (press only)
|
|
* 2nd time: left-click (press only)
|
|
* NB: press-only means that when the button is pressed, the
|
|
* KeyPress/ButtonPress and KeyRelease/ButtonRelease events are generated
|
|
* together sequentially; instead when the button is released, no event is
|
|
* generated !
|
|
*
|
|
* With the command
|
|
* 10<xx>0a 3500af03 (where <xx> is the mouse id),
|
|
* the mouse reacts differently:
|
|
* - it never sends a keyboard key event
|
|
* - for the three mouse button it sends:
|
|
* middle button press 11<xx>0a 3500af00...
|
|
* side 1 button (forward) press 11<xx>0a 3500b000...
|
|
* side 2 button (backward) press 11<xx>0a 3500ae00...
|
|
* middle/side1/side2 button release 11<xx>0a 35000000...
