I have a Kobo Forma reader (like a Kindle), on xubuntu versions up to
24.04 it automounted without problems. Now I'm running Debian 12 it's
failing to automount, I can't mount it manually either.
I get the usual messages at the Kobo end and fdisk shows me /dev/sdc
but no file system appears. In dmesg I see:-

Do I need a Windows/DOS driver of some sort? Or has something else gone wrong?
