Can I use interrupts while working with the USBSerial?

Hello! I am working with the FRDMKL25Z.

I tryed to use the following code to test if the timer interrupts works when I use the USBSerial class. The result is that ticker locks the code every timer overflows... why does that happen?

#include "mbed.h"
#include "USBSerial.h"

/*---Classes------*/
DigitalOut myled(LED1);
DigitalOut pte1(PTE1);
USBSerial pc;
Ticker t1;
/*---Functions---*/

void SerialCallback(void);
void T1Handler(void);

int main() {
    
    pc.attach(&SerialCallback);
    t1.attach(&T1Handler,1);
    
    while(1) {
        myled=1;
        wait(1);
        myled=0;
        wait(1);
    
    }
}



void SerialCallback(void){
  
        while(pc.readable()){
            pc._putc(pc._getc());
            }
    return;
    }
    
void T1Handler(void){
    
        pc._putc(0x32);
    
    return;
    
    }

OF COURSE! you cant use those functions inside an interrupt!!!
