If you were not superuser or ran xorriso under sudo, then the ownership
and permissions are a valid reason for being unable to read its content.
I do not generally advise to make backups as superuser. But since the
mounted USB stick probably contains files of many users with various
permission sets i now propose to become superuser or run xorriso under
control of program sudo:
sudo xorriso \
-for_backup \
-outdev usb_part1.iso \
-map /media/user/sid /

Well, it's the boss directory which we do not want to backup.
Nevertheless, Debian's build of xorriso run with settimg -for_backup
will record ACLs and Extended Attributes. Linux mount will not show them,
but xorriso will be able to restore them.
Have a nice day :)
