Check whether the power supply voltage for the USB port is less than 5V, in general, if it is 4.9V or more, the module's two USB ports can be used normally. If it is lower than 4.9V, the power supply may be insufficient and the USB port may disconnect. In this case, you should replace it with a USB port with sufficient voltage.
