Description:
The /sys/class/hidraw/hidraw*/device/speed file controls
reporting speed of Wacom bluetooth tablet. Reading from
this file returns 1 if tablet reports in high speed mode
or 0 otherwise. Writing to this file one of these values
switches reporting speed.

Description:
Attribute group for control of the status LEDs and the OLEDs.
This attribute group is only available for Intuos 4 M, L,
and XL (with LEDs and OLEDs) and Cintiq 21UX2 (LEDs only).
Therefore its presence implicitly signifies the presence of
said LEDs and OLEDs on the tablet device.

Description:
When writing a 1024 byte raw image in Wacom Intuos 4
interleaving format to the file, the image shows up on Button N
of the device. The image is a 64x32 pixel 4-bit gray image. The
1024 byte binary is split up into 16x 64 byte chunks. Each 64
byte chunk encodes the image data for two consecutive lines on
the display. The low nibble of each byte contains the first
line, and the high nibble contains the second line.

6.2 Native absolute mode 6 byte packet format
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 and 3 finger touch shares the same 6-byte packet format, except that
3 finger touch only reports the position of the center of all three fingers.
Firmware would send 12 bytes of data for 2 finger touch.
Note on debounce:
In case the box has unstable power supply or other electricity issues, or
when number of finger changes, F/W would send "debounce packet" to inform
driver that the hardware is in debounce status.
The debouce packet has the following signature:
byte 0: 0xc4
byte 1: 0xff
byte 2: 0xff
byte 3: 0x02
byte 4: 0xff
byte 5: 0xff
When we encounter this kind of packet, we just ignore it.

6.2.2 Two finger touch
~~~~~~~~~~~~~~~~
The packet format is exactly the same for two finger touch, except the hardware
sends two 6 byte packets. The first packet contains data for the first finger,
the second packet has data for the second finger. So for two finger touch a
total of 12 bytes are sent.

7.2 Native absolute mode 6 byte packet format
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
v4 hardware is a true multitouch touchpad, capable of tracking up to 5 fingers.
Unfortunately, due to PS/2's limited bandwidth, its packet format is rather
complex.
Whenever the numbers or identities of the fingers changes, the hardware sends a
status packet to indicate how many and which fingers is on touchpad, followed by
head packets or motion packets. A head packet contains data of finger id, finger
position (absolute x, y values), width, and pressure. A motion packet contains
two fingers' position delta.
For example, when status packet tells there are 2 fingers on touchpad, then we
can expect two following head packets. If the finger status doesn't change,
the following packets would be motion packets, only sending delta of finger
position, until we receive a status packet.
One exception is one finger touch. when a status packet tells us there is only
one finger, the hardware would just send head packets afterwards.

@ -65,6 +65,20 @@ the full state of each initiated contact has to reside in the receiving
end. Upon receiving an MT event, one simply updates the appropriate
attribute of the current slot.
Some devices identify and/or track more contacts than they can report to the
driver. A driver for such a device should associate one type B slot with each
contact that is reported by the hardware. Whenever the identity of the
contact associated with a slot changes, the driver should invalidate that
slot by changing its ABS_MT_TRACKING_ID. If the hardware signals that it is
tracking more contacts than it is currently reporting, the driver should use
a BTN_TOOL_*TAP event to inform userspace of the total number of contacts
being tracked by the hardware at that moment. The driver should do this by
explicitly sending the corresponding BTN_TOOL_*TAP event and setting
use_count to false when calling input_mt_report_pointer_emulation().
The driver should only advertise as many slots as the hardware can report.
Userspace can detect that a driver can report more total contacts than slots
by noting that the largest supported BTN_TOOL_*TAP event is larger than the
total number of type B slots reported in the absinfo for the ABS_MT_SLOT axis.
