PL2303 Driver on Mac – Can’t Find tty.usbserial Under /dev

installmacos

Installed the PL2303 Driver in my Mac, but I still can not find the tty.usbserial* under /dev.

I follow the PL2303 Driver to install the PL2303_MacOSX_1.6.1_20171018.zip in my Mac.

I installed the pkg, and restarted my Mac, but there is a difference between the manual and mine:

The manual:

The Manual

Mine MacOS:

And the most important is, under the /dev, I can not find any tty.usbserial*:

$ ls tty.*
tty.Bluetooth-Incoming-Port

EDIT-01

IDs in the manual:

Product ID: 0x2303
Vendor ID: 0x067b

My USB2.0-Ser!:

Product ID： 0x7523
Vendor ID：  0x1a86

EDIT-02

My macOS sierra version is 10.12.6 (16G1114).

EDIT-03

I tried install CH341SER_MAC_ZIP.html

But, now if I insert the USB into my Mac, my Mac will restart with the error on screen:

your computer will restarted because of a problem. Press a key or wait a few seconds to continue starting up.

and there is no USB2.0-Ser! now:

Best Answer

You have the driver for the prolific chipset AT-232 cable installed - VID 0x067b, PID 0x2303.

The device you have connected is not reporting as a prolific AT-232. The device you have connected is reporting as a QinHeng Electronics CH340 - VID 0x1a86, PID 0x7523.

I'd recommend trying the driver for the CH340 http://www.wch.cn/download/CH341SER_MAC_ZIP.html
