USB stick mounted as read-only CD-ROM

Question

I have a kingston encryptable USB stick, that when plugged into my laptop gets mounted as read-only.

I have followed the advice given here, but it does not work for me.

I have tried the following:

df -Th
/dev/sr0                    iso9660    13M   13M     0 100% /media/user/DTVP

(note that the drive is actually 4GB)

sudo chown user /dev/sr0
sudo chgrp user /dev/sr0

do not yield any output, same if I apply them to /media/user/DTVP

dosfsck /dev/sr0
fsck.fat 4.1 (2017-01-24)
open: Read-only file system

I also tried

getfacl /media/user
getfacl: Removing leading '/' from absolute path names
# file: media/user
# owner: root
# group: root
user::rwx
user:user:r-x
group::---
mask::r-x
other::---

and then try to correct in

sudo setfacl -m u:user:rwx /media/user

but still, the stick stays read-only. Curiously, on Nautilus it appears as a CD rom rather than a USB stick, and, I guess for the same reason, on GParted is not listed and cannot be reformatted.

Any pointers?

Edit: output of journalctl -f
