MacOS Catalina 10.15.7

I can't seem to get CH9102 devices working with this driver; but can drive CH340. Does anyone know why?

Steps:

  1. Installed ch34xVCPDriver.pkg and rebooted
  2. Attach no-name Robotdyn UNO+WiFi knock-off with atmega328p + ESP8266 and CH340 to mac - USB device found by OSX and Arduino flashes fine (as has many times before) on native arduino/osx or within Win10/virtualbox/osx
  3. Disconnect CH340 based device and cable
  4. Attach TTGO Display 3 with CH9102 and manufacturer-supplied USB2 to USBC cable to mac - USB device not found by OSX or Arduino

Based on a similar thread (there are a few out there) this doesn't work on OSX pre-Big Sur. Will test on Monterey.

Please note that: you should use the “tty.wchusbserialx” where “x” is the assigned device number similar to Windows COM port assignment.
