I have a digital camera (not exactly a digital camera, its a digital otoscope) that records video and images to an SD card that has a filesystem Teensy 4.1/USBHost_t36 does not recognize.
I confirmed a FAT32 partition does in fact exist on the card when connecting to a computer and appears in the windows disk manager as a drive with one FAT32 primary partition.
I can format the card using windows and the file system is legible to the teensy. The digital camera, however, insists the card be formatting when inserted into the camera which then "masks" the filesystem from the Teensy.
I have manually formatted and accessed files on two separate SD cards to confirm functional cards.
My question is twofold: is this an MTP-related issue and I should be using an additional library to access, and does anyone have suggestions on how to analyze an SD card with more granularity to try and find out what I might be able to do here.
