Mon, 13 Jul 2026 14:42:13 +0200

HID: hyperx: add driver for the HyperX QuadCast 2 mute buttonThe tap-to-mute button of the HyperX QuadCast 2 (03f0:07b4) is handledentirely in the device firmware. The firmware gates the audio internallybut never sends the Telephony "Phone Mute" usage (0x2f) that its own reportdescriptor advertises, and it does not touch the UAC feature unit either.Consequently neither an evdev key event nor an ALSA mixer change is evergenerated, and userspace has no way to learn that the microphone was muted:desktops keep showing the microphone as live, and conferencing applicationskeep displaying an unmuted microphone while transmitting silence.The mute state is reported through a vendor-defined collection instead: 06 c0 ff Usage Page (Vendor-Defined 0xFFC0) a1 01 Collection (Application) 06 c1 ff Usage Page (Vendor-Defined 0xFFC1) 85 77 Report ID (0x77) 09 f0 Usage (0xF0) 75 08 95 3f Report Size (8), Report Count (63) 81 02 Input (Data,Var,Abs)Pressing the button emits a 64-byte report on that collection: 77 06 00 00 ... microphone unmuted 77 06 01 00 ... microphone mutedwhere byte 1 identifies the mute event and byte 2 carries the resultingstate. As the payload is an opaque vendor blob carrying no HID usages,hid-input cannot map it and a hwdb entry cannot express it either.Add a driver that decodes the report and emits KEY_MICMUTE, which makes thebutton behave like any other microphone mute key.Note that the device reports the resulting absolute state, whereasKEY_MICMUTE is a momentary key that userspace acts on as a toggle, so thedriver emits one keypress per state change.Tested on a HyperX QuadCast 2 (03f0:07b4).Signed-off-by: Benjamin Blume Signed-off-by: Jiri Kosina List of files: /linux/drivers/hid/hid-hyperx.c
