lg4l's Introduction

Logitech 4 Linux

This project is intended to provide kernel modules to support various Logictech input devices including:

G110
G13
G15 (needs testing)
G15v2
G19
G510 (does not work on my device)

This work has been mostly done by a couple of friendly people on the Freenode IRC channel #lg4l

If you're looking for some help, best to drop by there and see if anyone's around.

Building

All going well, you should be able to just install your kernel headers and type

# make
# make install

Now load the correct module for your device, eg:

# modprobe hid-g19

The modules will now be available but the device will still be grabbed by generic-usb. Run the rebind script to put the new module in control of the device:

# ./rebind

lg4l's Issues

Unable to bind g15v1

Hi, I have a g15v1 keyboard and I have compiled the driver from 4.11 branch (i'm on debian stretch with kernel 4.9). I have an issue when binding the driver to device. When i do lsusb, the output is the following:

Bus 001 Device 042: ID 046d:c222 Logitech, Inc. G15 Keyboard / LCD
Bus 001 Device 040: ID 046d:c221 Logitech, Inc. G11/G15 Keyboard / Keyboard
Bus 001 Device 039: ID 046d:c223 Logitech, Inc. G11/G15 Keyboard / USB Hub

the rebind script try to bind the to the device 046d:c222 but the input device seems to be 046d:c221 ( since 046d:c222 is clearly related to the keyboard LCD) . So i tried to change the the id into rebind script but I get:

bash: echo: write error: No such device

tried to do it manually but I gate the same error

Thank you for your work

Review keyboard initialization sequences

Some "faking away with initialization" message seems to appear on all devices.
The initialization sequence seems to be reverse engineered with an USB monitor from the windows drivers until the device "worked". The stages and the messages exchanged at that phase seem to differ for each device, although the results are ignored by the driver.

Kernel crashes on module removal

Removing the hid-g13 module (with the G13 plugged in) causes the kernel to crash.

make && make install the modules
depmod -a
modprobe hid-g13
Click on the USB icon in virtualbox and enable the G13
sh rebind
G13 lights up, dmesg shows all is well
rmmod hid-g13

It then crashes - http://i.imgur.com/Qmceu.png

In hid-gfb.c, I tried moving the "fb_deferred_io_cleanup(info);" in gfb_free_framebuffer_work() to be the first thing done as this seem to be the order used when gfb_probe() fails. This seem to make it get a little further, but it still crashes on the vfree().

Ubuntu 18

After make install. Ik got a bunch off error messages and don't what to do. Afther make also, but that whas a missing depencie.

Project status

I found the kernel mailinglist threads, but they seem to dead end. Has this project stalled out or is there something in the works that is not visible or I have not found?

I appreciate the effort.

Pull Request #5 pending for a year now

Heyas, G510 support works just fine. Can you please merge my pr, #5 ?

hid_ginput crash with 3.13 and 3.14 kernels on start of g15 client utilities
