Hi all , I have connected Arduino Nano to the Jetson Xavier NX USB port.
After some time USB disconnects and reconnects back itself.

Python Code:
import serial

def readserial(comport, baudrate):
ser = serial.Serial(comport, baudrate, timeout=0.1) # 1/timeout is the frequency at which the port is read
while True:
data = ser.readline()
ser.flush()
if data:
print(data)

if name == ‘main’:
readserial(‘/dev/ttyUSB3’, 9600)

Error: ///“raise SerialException(
serial.serialutil.SerialException: device reports readiness to read but returned no data (device disconnected or multiple access on port?)”///

dmesg gives this: ///" override usb 1-2-port1: disabled by hub (EMI?), re-enabling…"///

is there a way to disable this feature.

Hi @akshay_hegde ,
This is a Jetson issue, moving.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Hi akshay_hegde,

Are you using the devkit or custom board for Xavier NX?
What’s your Jetpack version in use?

Please share the full dmesg and the steps how you reproduce this issue for further check.
