Unfortunately this Pi Zero device is pretty much useless for reading USB Messages and Writing USB Messages thru script for the following reasons:
As soon as I try to read in any kind of loop even with sleep 2s it "locks up the 1 cpu" and wifi never becomes available which means the device needs a complete sd card wipe and reinstall and redo all the work of the scrpts and retest - there needs to be a dedicated connection to the filesystem outside of ssh like on a mac i can touch the boot system, but not in windows....
HAS Anyone successfully connected a Raspberry Pi Zero in usb Gadget mode to a Windows PC and are able to send and receive USB messages over serial like xg_multi without the device freeze?![:(]( "Sad")
![:?:]( "Question")
![:geek:]( "Geek")
I have tried examples such as:also the while loop with sleep:I read about python scripts to do this instead of shell, tried to install pip failed to install pyserial library multiple ways
but was going to try to kick this script off after usb gadget for xg_multi was complete rather than inside the xg_multi in the bash script:

I have tried examples such as:
Code:
#log usb messages to output log sudo cat /dev/ttyGS0 > /usr/bin/xg_multi_output.logCode:
while IFS= read -r line; do echo "Received: $line" sleep 2s done < /dev/ttyGS0but was going to try to kick this script off after usb gadget for xg_multi was complete rather than inside the xg_multi in the bash script:
Code:
import serialimport time# Configure the serial portserial_port = '/dev/ttyGS0' baud_rate = 9600try: # Initialize serial connection ser = serial.Serial(serial_port, baud_rate, timeout=1) time.sleep(2) # Wait for connection to settle print(f"Connected to {serial_port} at {baud_rate} baud.") while True: if ser.in_waiting > 0: # Read line, decode bytes to string, and strip whitespace line = ser.readline().decode('utf-8').rstrip() # --- PARSING LOGIC HERE --- print(f"Received: {line}") # Example: if "TEMP" in line: parse_temp(line) # --------------------------except serial.SerialException as e: print(f"Error: {e}")except KeyboardInterrupt: print("\nExiting...")finally: if 'ser' in locals() and ser.is_open: ser.close() print("Serial port closed.")Statistics: Posted by mrkell28 — Thu Jan 29, 2026 9:45 pm
