corsair-void-driver

• Corsair Void headset family device driver for the Linux kernel
  • Includes the Corsair Void Pro / Elite / RGB headsets
  • This is experimental, expect issues
• Requires kernel headers to be installed
• Kernels before 6.10 are only supported up to tag v0.2
• Kernels before 6.4 are only supported up to tag v0.1

Build system

• make: Build the module
• make install: Install the module
• make clean: Clean the build directory
• A different build directory can be forced with BUILD_DIR=[DIR] make ...
  • Defaults to build
• Kernel headers are responsible for the install, look for /usr/lib/modules/[KERNEL VERSION]/extra/hid-corsair-void.ko to remove it
  • On some systems, this might be /usr/lib/modules/[KERNEL VERSION]/updates/hid-corsair-void.ko

Features

• Battery reporting
• LED support (on / off, brightness, colour)
  • I currently have no set plans to tackle this, but pull requests are welcome
  • For anyone attempting this, here's a rough check-list:
    • Software control mode on probe
    • Handlers for both mutes
    • Audio alerts when mute state changes
      • Audio alerts for wired devices
      • Share the code for this with sysfs
    • LED control functions
    • Sysfs LED support
• Sidetone support
  • (sysfs) set_sidetone: [0 - sidetone_max] (write-only)
  • (sysfs) sidetone_max (read-only)
• Misc device / kernel attributes
  • (USB) wireless_status (wireless only)
  • (sysfs) microphone_up: [0 / 1] (read-only)
  • (sysfs) send_alert: [0 / 1] (write-only), (wireless only)
    • If this can be done on wired headsets, feel free to submit a pull request
  • (sysfs) fw_version_[receiver / headset] (read-only)
• Wired, wireless and surround headset support
  • Wired and surround headsets aren't as well tested
    • If you have one of these, please file an issue with whether or not the sidetone works
