2012-09-25HID: hid-lg4ff: Adjust X axis input value accordingly to selected range.Michal Malý
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.

2011-08-04HID: lg4ff - Add range setting support and sysfs interfaceMichal Malý
Wheel range of certain Logitech wheels - namely Driving Force GT, Driving Force Pro, G25 and G27 can be adjusted. Minimu is 40 degrees, maximum 900. DFGT, G25 and G27 all use a common command, DFP uses another one. Range can be set from userspace by writing to "/sys/module/hid_logitech/drivers/hid:logitech/<dev>range". The driver use list to store range of each connected wheel; it's not possible to use driver_data in hid_device struct as it's already b hig-lg driver.

2010-09-22HID: Add support for Logitech Speed Force Wireless gaming wheelSimon Wood
The following patch adds support for the Logitech Speed Force Wireless gaming wheel. Originally designed for the WII console. Details on the protocol: http://wiibrew.org/wiki/Logitech_USB_steering_wheel This patch relies on previous patch: "Don't Send Feature Reports on Interrupt Endpoint" Logitech as produce a very similar wheel for the PS2/PS3, it is expected that this patch could also support the PS2/PS3 wheel if the USB ID's are added and (if required) the HID descriptor is modified.
