Macbook Pro 16-inch, 2019, macOS Ventura 13.2.1 (22D68). I plug in the GREENextreme CR-CFXB card reader, but it is not seeing the card. I see a blue light on the card reader when I insert the card, but I cannot see the card reader or its card on my Macbook Pro. Thoughts? Suggestions?

You can also use to transfer images to your Mac.
