The accelerometers/gyro on the Sixaxis are reported in the wrong
endianness (ie. not compatible with HID), so this patch intercepts
the report and swaps the appropriate bytes over.

Accelerometers are scaled with a nominal value of +/-4000 = 1G,
maximum value would be around +/-32768 = 8G.

Gyro on my device always reports -32768, might need some calibration
set within the controller.

Speedlink VAD Cezanne have a hardware bug that makes the cursor "jump" from one
place to another every now and then. The issue are relative motion events
erroneously reported by the device, each having a distance value of +256. This
256 can in fact never occur due to real motion, therefore those events can
safely be ignored.  The driver also drops useless EV_REL events with a value of
0, that the device sends every time it sends an "real" EV_REL or EV_KEY event.

- Add the quirk "NOGET" to make the wheel work at all in native mode.
- Replace the somehow broken report descriptor with a custom one to have
  separate throttle and brake axes.

As there are significant differences in the descriptor (original descriptor
"hides" the separate axes in a  24 bit FF00 usagepage, new descripter replaces
that with two individual 8 bit desktop.y and desktop.rz usages) I provided a
complete replacement descriptor instead trying to patch the original one.
Patching the descriptor seems not feasible as the new one is much larger.

Note: To actually test this you have to use the tool "ltwheelconf" to put the
DFP into it's native mode - See below for more info.

Background:
Most Logitech wheels are initially reporting themselves with a "fallback"
deviceID (USB_DEVICE_ID_LOGITECH_WHEEL - 0xc294), in order to make sure they
are working even without having the proper driver installed.

If the Logitech driver is installed it sends a special command to the wheel
which sets the wheel to "native mode", enabling enhance features like:
- Clutch pedal
- extended wheel rotation range (up to 900 degrees)
- H-gate shifter
- separate axis for throttle / brake
- all buttons

When the wheel is set to native mode it basically disconnects and reconnects
with a different deviceID (USB_DEVICE_ID_LOGITECH_DFP_WHEEL - 0xc298 in this
case).

I am working on a userspace tool [1] which does the switching from fallback to
native mode. During development I found out that the Driving Force Pro wheel
is not supported in native mode - quierk NOGET is missing and the throttle and
brake axes are reported in a combined way only.

Unfortunately, the device seems to have the same Vendor ID and Product ID
as YUREX leg-shakes sensors, and the commit 6bc235a2 ("USB: add driver

I believe that we can distinguish YUREX and the Wireless Presenter by

(bInterfaceProtocol==0), and recognize Wireless Presenter
(bInterfaceProtocol is keyboard or mouse) as generic HID.  (I don't have

The device reponds with 'invalid report id' when feature report switching it
into multitouch mode is sent to it.

This has been silently ignored before 0825411a ("HID: bt: Wait for ACK
on Sent Reports"), but since this commit, it propagates -EIO from the _raw
callback .

So let the driver ignore -EIO as response to 0xd7,0x01 report, as that's
how the device reacts in normal mode.

Sad, but following reality.

I've got a Tivo Slide bluetooth remote/dongle, which uses a fair number
of hid usages that aren't currently mapped in hid-input.c. I'd initially
written additions to hid-input.c with just this device in mind,
including some bits that were specific to the device. This go around,
I'm looking at adding/correcting as many generic HID usages from the HID
Usage Tables, version 1.12, as I can -- which also serves to enable all
but four of the buttons on the Tivo Slide remote[*].

Outside of fixing the obviously incorrect mapping of 0xc 0x45 from
KEY_RADIO to KEY_RIGHT, and making use of the new KEY_IMAGES (just added
in 2.6.39-rc4) for AL Image Browser instead of KEY_MEDIA, these are
purely additions, and thus should have no negative impact on any already
functional HID devices. Most of the added mappings seemed to be
perfectly logical to me, but there were a few that were mapped on more
of an "I think this makes the most sense" basis.

[*] I'll handle the last four tivo buttons via an hid-tivo.c follow-up.

the current implementation requires the devices to report
HID_DG_CONTACTCOUNT to set the last_field_index value.
However, devices reporting in serial mode (DWAV and PenMount)
do not send this field.
Other devices (3M) add other fields in the reports descriptor
that are not multitouch related at the end, thus the need to
add a special case in the default case when handling events.

A first work around has been set up but with PenMount devices,
we have reached the limit.

The idea is to calculate the last_field_index by relying only on
multitouch fields the device send. This allows us to remove
the handling of non-multitouch events in hid-multitouch, and
guarantee that the function mt_emit_event is always called.
