Adding a Corsair Device

This guide explains how to add support for a Corsair headset to HeadsetControl.

Quick Check

Most Corsair headsets use the same protocol, so your device might work by simply adding its Product ID to an existing implementation.

Exception: The Virtuoso and HS series use different protocols and may need separate implementations.

Step 1: Find Your Device ID

./headsetcontrol --dev -- --list

Look for your Corsair headset (Vendor ID 0x1b1c) and note the Product ID.

Step 2: Check ALSA (Linux)

alsamixer
# Press F6, select your headset
# Look for "Sidetone" control

If sidetone appears in ALSA, it can't be controlled via HID (but battery and other features may still work).

Step 3: Add Your Product ID

Most Corsair headsets can be added to lib/devices/corsair_void_rich.hpp:

// Find the PRODUCT_IDS array and add your ID
static constexpr std::array<uint16_t, N> PRODUCT_IDS {
    0x1b27,  // VOID PRO
    0x1b2a,  // VOID PRO Wireless
    0x1b23,  // VOID USB
    0x1b2f,  // <- Add your product ID here
};

Also update the array size N to match the new count.

Note: You don't need to modify device_registry.cpp - the device is already registered there. Just adding the product ID to the array is enough.

Step 4: Build and Test

cd build
cmake ..
make

# Test your headset
./headsetcontrol -b      # Battery
./headsetcontrol -s 64   # Sidetone
./headsetcontrol -l 1    # Lights on

If It Doesn't Work

If the standard Corsair protocol doesn't work for your headset:

  1. Use developer mode to explore:

    ./headsetcontrol --dev -- --list --device 0x1b1c:YOUR_ID

  2. Capture USB traffic with Wireshark (see ADDING_A_DEVICE.md)

  3. You may need to create a new device class - use corsair_void_rich.hpp as a template
