Write access to USB

[notoneofmy <notoneofmyseeds@gmx.de>]

I format, ext2, or ext3, a USB using gparted, which is started as root,
and can only be, in the Terminal.

Once formatted and partition created, I cannot write to the USB stick,
unless I issue a Chown 777 command in terminal.

However, in the Terminal, I'm able "mkdir xyz" and it works

I cannot do this in the File Manager. I'm on Jessie with xfce4.

The stick itself is automatically mounted after gparted is done with it.

It did not use to be like this.

Thanks in advance.
