Hello. I recently bought a brand new MacBook Pro (Big Sur OS). I downloaded the latest Calibre and transferred all of my books onto it. However, whenever I plug in my Kindle 7 (9th Gen), Calibre doesn't recognize it. Meanwhile, my old MacBook Pro and Calibre still do recognize my Kindle.

I've restarted my Kindle, Mac, and Calibre but it doesn't work. I've also gone into my Kindle preferences and made sure the USB preferences say "File Transfer". I've gone into the Calibre preferences and clicked "Debug Device Detection" in the Misc. tab. It said no device was attached.

I noticed that whenever I plug my Kindle into my old Mac, Calibre will pop up a notification that says I have to change the USB preferences on my Kindle to transfer files. Calibre on my new Mac doesn't have that notification.

Is it possible that the thunderbolt adapter and Kindle wire aren't working together? Or is it the new Mac or the new Calibre that's having problems?

Thank you.
