usb_cdc.data with the Seeeduino Xiao M0

Question

I make my first steps with CircuitPy and try to parse some data over the USB.

The data is coming from a python script running on my PC.

**boot.py **

import usb_cdc

usb_cdc.enable(console=True, data=True)

after a power cycle I have two COM ports but if I try to connect to COM11 it looks like the COM port is frozen. I can't type or receive anything. If I open COM10, which is my REPL everything works as expected.

this is one of my 100000 attempts:

import time
import usb_cdc

uart = usb_cdc.serials[1]

#s = bytearray("hello\n\r".encode())

while True:
    #uart.write(s)
    
    incoming = uart.readline().decode("utf-8")
    print (incoming)


    time.sleep(1)

Can somebody pleas point me in the right direction?

Thank you!
