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