I think you are trying to get serial console access to the rockpro64 by plugging in a USB serial adapter in one of the USB ports. Unfortunately, to get serial access to the RP64, you need a 3V3 TTL serial adapter (FT232 or others) that plug into the GPIO pins.

The guide to get this working is here:

Hi, 
So that means i can't use usb port for serial communication?
As i have done serial communication with gpio pins (6,8,10) and used a usb to TTL converter. That is done. 
What i asked to use USB port to send serial data for serial communication. Can i do that?

@martinayotte

Yes, The device at the receiving end is a serial +-12v. So please suggest how to achieve that.
And anyhow i have to use a TTL to serial converter in between but i want to distinguish two possibilities-
1) one is i use gpio pins(6,8,10) and then use converter
2) If i want to use one of the USB port instead of GPIOs so how can i do that?
Thanks.
