About

This is a simple Linux driver (written in C++) for the Tourbox Neo. (The manufacturer frustratingly refused to provide a Linux driver, so I decided to write one)

This driver lets you use the device as a rudimentary keyboard and mouse combo -- the D-pad controls a virtual mouse, and the various keys perform different functions (see docs folder for full list).

Usage

Compile the driver via C-Make.

$ cmake CMakeLists.txt
$ make

In a separate window, open dmesg.

Since the device will be writing to /dev/uinput, you need to either:

(a) Run the executable (Tourbox_Linux_Driver) as root, passing in the path to the serial port for your device. This is either /dev/ttyACM0 or /dev/ttyUSB0 on most distributions, check your dmesg output when you connect your device to be sure.

(b) Change the permissions on /dev/uinput

Whatever you decide to do, after running the executable you should see an entry in the dmesg window with the device:

input: Custom Tourbox TBG_H Driver (Keyboard/Mouse) as /devices/virtual/input/input48

This tells you it's ready for use. When you're ready to stop using the driver, simply Ctrl + C (SIGINT) the program

If you'd like to change the functionality provided by the driver, you can use Xmodmap to create your own keymap.

Whenever I launch this, all the command prompt gives me is:

And it keeps looping.

GCC 12 build issue: `error: loop variable ‘keyType’ creates a copy from type ‘const std::pair<const KeyType, int>’ [-Werror=range-loop-construct]`

Hey whenever I try to use the make command, here's what happens:
Consolidate compiler generated dependencies of target TourBox_Linux_Driver [ 50%] Building CXX object CMakeFiles/TourBox_Linux_Driver.dir/main.cpp.o In file included from /home/wayne/Tourbox_Linux_Driver/cpp/main.cpp:23: /home/wayne/Tourbox_Linux_Driver/cpp/uinput_helper.hpp: In function ‘void registerKeyboardEvents(int)’: /home/wayne/Tourbox_Linux_Driver/cpp/uinput_helper.hpp:87:21: error: loop variable ‘keyType’ creates a copy from type ‘const std::pair<const KeyType, int>’ [-Werror=range-loop-construct] 87 | for (const auto keyType : keyMap) | ^~~~~~~ /home/wayne/Tourbox_Linux_Driver/cpp/uinput_helper.hpp:87:21: note: use reference type to prevent copying 87 | for (const auto keyType : keyMap) | ^~~~~~~ | & cc1plus: all warnings being treated as errors make[2]: *** [CMakeFiles/TourBox_Linux_Driver.dir/build.make:76: CMakeFiles/TourBox_Linux_Driver.dir/main.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/TourBox_Linux_Driver.dir/all] Error 2 make: *** [Makefile:91: all] Error 2

How to Map This

So I read that you can remap the buttons using Xmodmap. I've read up on the Arch wiki on how to use it, but it only seems to relate to the keyboard. I've also run xev just to get an idea as to the input, but some of them read the same (dial clockwise, knob counterclockwise). Anybody know where to point me for mapping this bad boy?

Cleanup/Refactor

  • Refactor uinput_helper.hpp -- stop passing the file descriptor around so much.
  • Check return value of read(2), ioctl, write and all other syscalls
  • Don't use array of single value
  • Make keymap const (then use at instead of operator[])

Issues with Tourbox Elite - can't reconnect to device after its been unplugged

I've been trying to get my elite controller to work and have discovered something unusual:
I can read input data from /dev/ttyACM0 initially when plugged into USB, however, if I disconnect the device and reconnect it, I can no longer read data. Only if I boot into Windows and launch the tourbox driver, then I can boot back into Linux and read from the device. Note that simply rebooting Linux does not seem to fix the issue.

Simple reproduction:

# Connect controller
sudo stty -F /dev/ttyACM0 raw
sudo cat /dev/ttyACM0 # and press some inputs
# Disconnect controller and repeat

The vibration motor also does not engage on input so I expect that this is triggered by writing some data to the device. I've been looking at the data produced in Wireshark, however, I expect this is overkill since this also includes all the USB header information as well, although I'm not sure if there is a simpler sniffing method.

Unwanted conflict with Logid (Logitech Drivers) driver

Upon successfully installing the driver, my programmed Logitech MX Master 3 (LogiOps) key binds revert to their default config despite the logid cfg file still having my bind configurations. Restarting and shutting down the system does not improve the issue.

Checking dmesg, the virtual device seems to stay despite already exiting the program.
