You can also watch the Mac’s log to see what the operating system does: If the UNO appears, what product and vendor ID does it have? What should I see and how can I possibly manually insert into kernel?ĭoes the UNO appear in the System Information application (section Hardware / USB)? If not, it’s likely an electrical problem such as a charge-only USB cable, a damaged USB connector or cable. I used ‘kmutil showloaded’ to get a list of loaded USB kernel extensions Ĭom.Ĭom.Ĭom.īut none seem to relate to serial USB or CH340. My UNO is running the CH340 chip so I need a driver loaded in my MacBook. I was expecting to see cu.usbserial or similar. Whether I connect my UNO or not the only driver I can see is cu.BLTH No surprise there.Ĭan you provide a screenshot of the USB section of the System Information application in macOS (click on Hardware / USB)? If I unplug the serial device, all remain the same except the usbserial device disappears. The attached hub can supply more power to the USB port than my laptop, which is why I tried it for a few attempts. The number changes depending on which USB port I’m using, I’ve tried a few both direct and via an attached hub. No, it’s used as a command-line argument. in platformio.ini)? If so, what’s the exact path? Have you configured the device path for the serial device somewhere (e.g. The message says it’s coming from serial.py. It shows up on the command line in the output from esptool.py. Pretty much all commands try for a while, then end with that message. What action results in the message “Device not configured”? Where and how is this message shown? Dropping all the way down to screen rather than using the tool is also getting me nothing - screen exits as soon as I apply power to the Tuya module. I can occasionally see the Rx light on the USB serial device flash a few times, but have yet to get any readable bytes. The simple commands include reading the chip id, reading the mac address, reading the flash id. At this point, I’m trying only a few simple read commands to try to get anything at all from the device, and getting nothing at all. Espressif supplies a tool (esptool.py) to do the upload. I want to upload Tasmota firmware to a Tuya TYWE3S module that contains an Espressif 8266. What do you want to use the serial device for? Uploading firmware? Output from device? What hardware do you use? What exact version of the CH340 does it use?
