Based on my experience with the Usb-can Analyzer, you must select a baud rate of 2,000,000 in the settings. You will know the update is complete when the TX and RX LEDs flash exactly once; at that point, you can use it in the vehicle, ensuring the baud rate in RealDash is also set to 2,000,000 and the CAN speed is set to 500kbps.
Baud rate 2M it will flash once when plug in the usb? Still configuring to connect with Link G4x.
The modification must be done via CAN_ USB software.
