In 2 earlier cameras, a new card it had no problems recognizing. Thats my clue. The cannons usb port is still functioning so the card has only been out of it once, before digikam grew a cannon driver with the buster release. How I interpret that clue is driven by my electronics troubleshooting history which starts in about 1950 when I quit school and went to work as a tech. That fed me well for the next 52 years, and still does.
