Kobra 3 Max investigation

On the K3:

  • The JST is connected to a SGM7227 (High Speed USB 2.0 Analog Switch) and then to a GL852G (Genesys Logic USB 2.0 Hub Controller)
  • I don't "see" those chips on the K3M board though from the pictures I have

On the K3M:

  • SGM7227 and GL852G are missing
  • Connecting the USB shows a Genesys Logic USB2.0 Hub device (05e3:610)
    • USB connection works, but it just exposes the internal USB hub with access to the camera and the other ports
    • Download mode through USB doesn’t seem to be accessible from there

Test on K3M:

05e3:610 > Genesys Logic USB2.0 Hub
