Range limiting command for the Driving Force Pro wheel is only a FF_SPRING
effect so that the wheel creates resistance when the user tries to turn it past
the limit. It is however possible to overpower the FFB motors quite easily which
leads to the X axis value exceeding the expected limit. This confuses
games which dynamically adjust calibration using the highest/lowest min and max
values reported by the wheel. Joydev device driver also doesn't take in account
any changes in an axis range after the joystick device is created.
This patch recalculates received ABS_X axis value so it is always in
<0; 16383> range where 0 is the left limit and 16383 the right limit.
Logitech driver for Windows does the same thing. As for any concerns about
possible loss of precision, I compared a large set of raw/adjusted values
generated by "mult_frac" to values returned by the Windows driver and I got
a 100% match.
Other Logitech wheels will probably need a similar fix, but I currently lack
the information needed to write one.

8cef908235 ("USB HID: add support for dynamically-created quirks")
876b9276b9 ("USB HID: add 'quirks' module parameter")
and as such, his copyright rightly belongs to
drivers/hid/usbhid/hid-quirks.c file.
However when generic HID code has been converted to bus and individual
quirks separated out to individual drivers on the bus, the copyright has
been blindly transfered into all the tiny drivers, which actually don't
contain any of Pauls' copyrighted code.

This is the first out of five patches me and Simon Wood (CC'd) have been
working on. It separates the handling of Logite from the generic lgff driver
and adds additional features specific for the Logitech wheels, namely
- Native mode support for Driving Force GT, Driving Force Pro, G25 and G27
wheels Every Logitech wheel reports itself as generic Logitech Driving Force
wheel (VID 046d, PID c294). This is done to ensu wheel will work on every USB
HID-aware system even when no Logitech driver is available. It however limits
the capabilit wheel - range is limited to 200 degrees, G25/G27 don't report the
clutch pedal and there is only one combined axis for t brake. The switch to
native mode is done via hardware-specific command which is different for each
wheel. When the wheel receives such command, it simulates reconnect and reports
to the OS with its actual PID.
- Adjustable wheel range DFGT, DFP, G25 and G27 have variable range of the
steering wheel. The range is limited by applying a maximum constant when the
wheel is turned beyond the allowed range. The limit as also set by a
hardware-specific command. There is a comm command for DFGT, G25 and G27 and
another one for DFP. It is probably possible to use the DFP command to limit
the range other Logitech wheels too, but this is not supported by the official
Logitech driver for Windows. The patch adds a sysfs interface which allows for
the range to be set from userspace.
- Fixed autocentering command All Logitech wheels support FF_AUTOCENTER effect.
The original implementation in the lgff driver didn't work well with patch
fixes it. According to USB communication sniffs the Formula Force EX (pretty
much rebranded original Driving Force accept the generic autocentering command,
this issue is also addressed by the patch
There are still some features this patch doesn't cover, but since some of them
will most likely require modifications of memless driver we have decided not to
include them yet.
As first we decided to move the handling of Logitech wheels from hid-lgff
driver to hid-lg4ff driver (originally used fo At also adds PID of Logitech
Driving Force GT.

- 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.
