esp8266 workshop part 1 step 1 CH340G USB tty not showing mac os

*****this is resolved now ****

hi Binnie

i have installed the driver successfully, restarted mac, however, i am not able to find new tty.

as per readme file there should be new device similar to tty.wchusbserial*


After the installation is completed, you will find serial device in the device list(/dev/tty.wchusbserial*), and you can access it with serial tools.

If you can’t find the serial port , you can follow the steps below:

  1. Open terminal and type ‘ls /dev/tty*’ and then you will see devices like tty.wchusbserial;
  2. Open ‘System Report’->Hardware->USB, the right side is “USB Device Tree” there will

be device named “Vendor-Specific Device” and check if the Current is normal.


my mac book shows below

nagars-MacBook-Pro:dev nagar$ ls -lrt tty.*

crw-rw-rw-  1 root  wheel   21,   2  1 Jul 09:40 tty.SOC

crw-rw-rw-  1 root  wheel   21,   0  1 Jul 09:40 tty.MALS

crw-rw-rw-  1 root  wheel   21,   4  1 Jul 09:40 tty.Bluetooth-Incoming-Port

Since I am not getting any success with Part 1 / WIFI, i am doubting incomplete installation of driver.

Please advise.
