Hi, first time caller...
Originally posted this is Linux Questions' Hardware subforum. Copying and pasting the tasty bits:
Trying to mount a thumb drive and an mp3 player under Debian testing
(buster), got a "filesystem vfat not found" message from the
automounter.
Tried "sudo modprobe vfat," got an "operation not permitted."
Modinfo did find the vfat module, so at least there's that.
Both the kernel and the vfat module are the same version, 4.19.0-1-amd64.
dmesg did not report anything interesting. I can post a tail or grep for something if somebody asks.
I did verify that my user account had access to the mount point. I also repeated the modprobe su-ed as root. Same error message.
I verified that the thumbdrive is fat32 (which vfat should handle, if I could get the module to load).
Did a cat /proc/devices got what I *think* is a list of numbers associated with all the devices on my system. Not sure how to get the vfat module to cough up what number it's trying to grab. I can post the cat /proc/devices list if anybody asks.

Not sure what that "ERROR: Bad version passed" means, but it looks important.
Any suggestions, guys?
