Do you have a free PCI express slot on the motherboard? If so, you could consider adding a card such as this: https://www.newegg.com/startech-com...express-to-serial-port-card/p/N82E16815158462
no.I Don't have this unfortunately
I had a similar issue with a different device. Make sure the drivers for the USB-to-DB25 cable are correctly installed.
