Using #include "USB.h" causes the device to not be found

[coco]

#include "USB.h"
void setup() {
USB.begin();
}

After importing and initializing USB, val drivers = UsbSerialProber.getDefaultProber().findAllDrivers(manager) will not be able to find the device. Delete #include "USB.h" and USB.begin(); before it can work normally. Please help to find out what the problem is.
