Problem with ESP32 connected to USB2. USB3 - seems OK. - erikbotta - 06-22-2020
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:

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:
