well it still uses the umount -l (lazy umount) in the /etc/local/Kobo/udev scripts. lazy umount only makes the filesystem invisible. it does not umount anything at all, as long as the filesystem is still in use. thus you export mounted filesystems and the result is corruption.
and the kobo device never reports any error so no one knows that there is a problem or what triggers it or how to fix it
remove the -l option and the script would run into "filesystem is busy" errors instead. e.g. it used to happen when connecting to usb from inside the kepub reader or at least that was the case years ago when I wrote
UsbDebug to try and track down the culprits (outdated by now)
remove the -l and add a few loops of retry umount and it'll still work as long as the filesystem would unbusy itself eventually
but if something blocks the filesystem permanent, with this fix you'd lose usb connectivity altogether, and end up locked out if you don't have another channel like telnet/ftp to access the device
maybe if it fails to umount five times, it should umount -l then display a warning message on the screen just to notify that there was a problem ...
