Hi all.
I am using platform.io framework in vs code on PBP and having problem with communication to ESP32 dev kit from USB2 (right) port.
For example when I am running monitoring of ESP32 serial port I get errors:

Code:

Value 1:249.71 Value 2:94.25 Value 1:153.50 Value 2:251Exception in thread rx: --- exit --- Traceback (most recent call last):   File "/home/erik/.platformio/penv/lib/python3.8/site-packages/serial/serialposix.py", line 500, in read     raise SerialException( serial.serialutil.SerialException: device reports readiness to read but returned no data (device disconnected or multiple access on port?) During handling of the above exception, another exception occurred: Traceback (most recent call last):   File "/usr/lib/python3.8/threading.py", line 932, in _bootstrap_inner     self.run()   File "/usr/lib/python3.8/threading.py", line 870, in run     self._target(*self._args, **self._kwargs)   File "/home/erik/.platformio/penv/lib/python3.8/site-packages/serial/tools/miniterm.py", line 445, in reader     data = self.serial.read(self.serial.in_waiting or 1)   File "/home/erik/.platformio/penv/lib/python3.8/site-packages/serial/serialposix.py", line 509, in read     raise SerialException('read failed: {}'.format(e)) serial.serialutil.SerialException: read failed: device reports readiness to read but returned no data (device disconnected or multiple access on port?)

After some good reading it failed.
If I use USB3 (left) port. Everyhing is fine.
