Testing has shown that, as expected, the MX3000 receiver is fully compatible with the existing 27MHz receiver support in hid-logitech-dj.c. After this the only, presumably also compatible, receiver id left in hid-lg.c is the USB_DEVICE_ID_S510_RECEIVER / 0xc50c id.

2019-04-23HID: logitech-dj: add support for 27 MHz receiversHans de Goede1-2/+0
Most Logitech wireless keyboard and mice using the 27 MHz are hidpp10 devices, add support to logitech-dj for their receivers. Doing so leads to 2 improvements: 1) All these devices share the same USB product-id for their receiver, making it impossible to properly map some special keys / buttons which differ from device to device. Adding support to logitech-dj to see these as hidpp10 devices allows us to get the actual device-id from the keyboard / mouse. 2) It enables battery-monitoring of these devices This patch uses a new HID group for 27Mhz devices, since the logitech-hidpp code needs to be able to differentiate them from other devices instantiated by the logitech-dj code.

2012-09-25HID: hid-lg4ff: Adjust X axis input value accordingly to selected range.Michal Malý1-0/+3
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 - Move handling of Logitech wheels to lg4ff driverMichal Malý1-8/+11
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.

2011-06-07HID: Fix Logitech Driving Force Pro wheelMichael Bauer1-1/+73
- 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.

2011-05-03HID: add support for Logitech G27 wheelPeter Gundermann1-0/+2
Gere's a small patch to add support for the Logitech G27 wheel, since the prior patch only added FF support for the Driving Force Pro and G25. The patch contains the changes from the G25 and DFP, too. I tested the changes with wine/LFS and got full support for all axes and buttons.

2010-12-10HID: Add and use hid_<level>: dev_<level> equivalentsJoe Perches1-8/+7
Neaten current uses of dev_<level> by adding and using hid specific hid_<level> macros. Convert existing uses of dev_<level> uses to hid_<level>. Convert hid-pidff printk uses to hid_<level>. Remove err_hid and use hid_err instead. Add missing newlines to logging messages where necessary. Coalesce format strings. Add and use pr_fmt(fmt) KBUILD_MODNAME ": " fmt Other miscellaneous changes: Add const struct hid_device * argument to hid-core functions extract() and implement() so hid_<level> can be used by them. Fix bad indentation in hid-core hid_input_field function that calls extract() function above. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
