I am trying to interface with the micro usb uart and not having any luck.
I have tried with a micro usb USB to serial chip CH340 (Driver installed)
https://cdn.sparkfun.com/datasheets/Dev/Arduino/Other/CH340DS1.PDF
I have tried with a 3 in 1 EFT Chimera FRP dongle that support USB TTL (Driver installed)
I have tried plugging in a Micro USB cable that is usb 2.0 with data pins (Nothing shows up in device manager)
I read over the pdf for the product. Doesn't indicate anything other then UART port
Any uart refered in the forum are the 4 pins from older models.
Even tried a otg dongle. No go.
What hardware/cable/serial device do I need to interact with the micro usb UART port?
I have set flow controll off, bitrate 115200 used putty and hyperterminal
@EHCanadian
Any Micro USB cable should do. Have you tried using this driver used on a managed switch? Please click here.

I have added the driver that you have linked to.
Silicon Labs CP210x USB to UART Bridge is present.
Now to figure out the port settings to communicate.
Can you try to use the following settings?
Speed 9600
Data bits 8
Stop bits 1
Parity None
Flow control XON/XOFF

You have to find the virtual COM port on the Windows system - however, both PuTTY and Hyperterminal should "see" it.
I had to set the broadrate to 115200. That granted me bios access.
Once the bios boot was completed I had to set the rate to 9600 to
access the linux text installer or the terminal. Got machine gibberish.
The serial only worked for text mode install media.
This also granted me a look behind the curtion on a few old configuration
that always failed so overall. It was a plesent experince.
