Hi Dennis, Good day to you
I have given permission by running sudo chmod 0777 /dev/ttyUSB0 Now I am able to open in putty but not receiving any data from bbb. Seems the issue with usb to serial cable. I got similar cable what you just mentioned on amazon. Probably I would try to procure one from adafruit. Thank you, it was of great help to me. I would check with different cables and come back if problem persists.
