Perhaps the first thing to figure out is the filesystem being used by the camera, otherwise I assume the card is useless. The default fs for such a card is exFAT, and the camera might just force that to be the case if it dislikes what you feed it. > According to the specs, the builtin card reader of the T480s is SDXC > compatible.

The kernels in bullseye support exFAT, but older releases will require the exfat-fuse and exfat-utils packages. Apparently bullseye can still use exfat-fuse with the new exfatprogs package, but I've not tried that.¹ > Needless to say, my SDHC cards (up to 32GB) work fine in this machine. Yes, because they're probably formatted as vfat. ¹ I toyed with exFAT as a Windows/linux shared backup format, but the advantages weren't sufficient to counter the complications. Cheers, David.
