They probably have the hardware run in USB-Serial mode (rather than the usual USB-HID mode of controller, keyboards and mice which has no capability to upload any significant data - beyond LED status - to the device) and then just push the firmware into the Serial Device their hardware appears at in that mode.

Yes but only in Chromium-based browsers as only those support the direct USB connection to the device.
