USB serial driver for ESPHome Flasher for Big Sur about esphome-flasher

[miguelarios]

here are my logs with the latest driver from here: https://www.silabs.com/community/interface/forum.topic.html/vcp_driver_for_macosbigsur110x-SWJK

Using '/dev/cu.SLAB_USBtoUART' as serial port.

Is this a duplicate of #39?

Yes this appears to be the same issue as the other. I just used the USB Serial device that showed up in the GUI with the command line command with -p flag and it worked just fine.

cd /Applications/ESPHome-Flasher/Contents/MacOS
./ESPHome-Flasher -p /dev/cu.usbserial-0001 /Users//Downloads/aqua1_hub.bin

Hey thanks. I think the difference with me was that it couldn't find the ESP despite the serial device being found under devices. What I found out was that to have the ESPHome GUI find my ESP was I had to hold the enable push button to wake up the ESP. This is how I was able to program. I think this is due to the module I bought.

I found this solution: https://forum.arduino.cc/index.php?topic=702144.msg4793318#msg4793318

1.- Open ~/Library/Arduino15/packages/esp8266/hardware/esp8266/2.7.4/tools/pyserial/serial/tools/list_ports_osx.py
2.- Comment out lines 29 and 30 and append these lines:
   iokit = ctypes.cdll.LoadLibrary('/System/Library/Frameworks/IOKit.framework/IOKit')
   cf = ctypes.cdll.LoadLibrary('/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation')

That worked well for me!
