Q: After powering on, the detected USB port keeps resetting and restarting?
Check whether the USB port's supply voltage is below 5V. Typically, the USB supply voltage should be above 4.9V, and both USB ports on the module should work normally. If it is below 4.9V, insufficient power may cause the USB port to disconnect. In that case, use a USB port that provides adequate voltage.
