USB-Endoscope: reconstructing Usee Plus USB video streaming

USB-Endoscope reconstructs the i4season Usee Plus endoscope’s vendor USB video protocol in a local WebUSB viewer. The author traced the Android app’s USBDEVFS calls with Frida and documented two stream-start control transfers followed by YUYV422 frames from bulk endpoint 0x82. The application displays live video and saves photos or recordings.
