Follow the steps below and try if it fixes your issue.

Open the terminal and type the commands

sudo mkdir /media/$USER
sudo chown $USER.$USER /media/$USER

What file system does the USB partition use?
When you last unplugged it, did you safely remove it in the OS before physically removing it?

To actionparsnip: yes last device was safely removed.

Thanks Subin Hutton, that solved my question.

It would be best if this could be set during setup, or wouldn't that be possible?
BTW: Thanks a lot!

I had the same problem, and used this trick to fix it :
sudo mkdir /media/$USER
sudo chown $USER.$USER /media/$USER

it is not very convenient!
