I have recently installed Home Assistant on an HP TP630 and implemented a number of add-ons successfully. I now want to add an ESP32-S3 device which is plugged into a USB port, but when I go through the ESPHome process it fails at the point where I select “PREPARE FOR FIRST USE”. After a minute or two I get the message “Failed to initialize…”. The device is recognised in Windows with the appropriate CP210x drivers, so I assume it is basically OK, but if I type “dmesg | grep tty” in Home Automation Terminal I see the line:
“usb 1-1.3 cp210x converter now attached to ttyUSB0”
immediately followed by:
“cp210x ttyUSB0: cp210x converter now disconnected from ttyUSB0”
so I wondered if I needed to do something else to recognise the device before running through the ESPHome process?
