CD/DVD writer (Burner) not communicating with Mac using USB

I was in communication with "Limnos" about my DVD writer failing to communicate with my Mac. His reply received on 29 Nov 2018 but the post is now gone.

The suggestion was to try my writer on another computer to see if it works. Finally I have an answer from my Son-in-Law, he connected the writer to his Windows 10 laptop and proceeded to write not only DVD's but also CDR's.

This reminds me of another episode where my Mac would not communicate with a USB device. My card reader. To cut a long story short when I connected my old (2008) wired keyboard to my Mac the card reader worked perfectly???? I tried my writer this way but it still will not communicate with the Mac, I get an error message which say's, failed connection and an error code which I cannot remember, but the error code has been discussed on these forums previously.
