If LConnect 3 still shows USB is not detected after connection, and HydroShift II is not detected in Device Manager, it may be due to lack of power from the connected PWM port. Please enter your BIOS and set the connected PWM port (recommended CPU_FAN or AIO_PUMP or PUMP ) to PWM/DC mode instead of Auto. Make sure to set the port to full speed.
