My MacOS Big Sur cannot detect the USB. Yes, I can see these drivers: /System/Library/DriverExtensions

  • com.apple.DriverKit-AppleUSBCHCOM.dext
  • com.apple.DriverKit-AppleUSBFTDI.dext
  • com.apple.DriverKit-AppleUSBSLCOM.dext

  1. My cable work with other ESP32 modules

  2. In the Hardware->USB, I got this output:

    Product ID: 0x7522
    Vendor ID: 0x1a86
    Version: 2.64
    Speed: Up to 12 Mb/s
    Location ID: 0x14200000 / 3
    Current Available (mA): 500
    Extra Operating Current (mA): 0

  3. Before using your approach, I install other USB drivers and already uninstall all of them using your guide

  4. Wemos D1 which use CH340C works. But LilyGo T-io Mac OS, Linux driver for CH340K · Issue #3 · LilyGO/LILYGO-T-OI · GitHub which uses CH340K doesn’t work
