Thanks for reaching out!
Perhaps what you can try to apply a simple USB hub to the USB port that you've successfully used. I'm referring to something similar to what is discussed at https://forum.allaboutcircuits.com/threads/simple-2-port-usb-2-0-hub.72097/.
Maybe this approach works better for your project.
