Detecting Firmware Version

facecam-probe detect    # Shows firmware field
facecam-probe topology  # Shows bcdDevice raw value

The firmware version comes from the USB bcdDevice descriptor. 0x0409 = firmware 4.09.

Firmware Update

Firmware updates can only be performed via Camera Hub on Windows or macOS. There is no Linux-native update mechanism.

If you're on firmware < 4.00:

  1. Borrow a Windows or Mac machine
  2. Install Camera Hub
  3. Connect the Facecam and follow the update prompt
  4. Verify on Linux: facecam-probe detect should show 4.09
