Ports (COM 3) not working

Hi, first post here hoping someone can help me with this.

I am using a new Lenovo laptop DRBA76TP. I am trying to set up a desktop CNC router machine . It has 2 USB ports on the right side. The CNC machine wants com port settings which are absent.

My first problem was that there were no port settings in the device manager so I highlighted the LAPTOP DRBA76TP label, went into Actions and added legacy hardware and was able to get the Ports (COM & LPT)with com 3 installed, but I am getting a message that says, "Windows cannot determine the settings for this device. Consult the documentation that came with this device and use the Resource tab to set the configuration. (Code 34)."

I have no idea on how to proceed from here.
