/media/usb0 is the mount point only.

The USB was formatted as fat32 filesystem so in 'usbmount.config' are
lines for this:
FS_MOUNTOPTIONS="-fstype=vfat,gid=floppy,dmask=0007,fmask=0117"

I don't want to mount it but want to ,et it mount automatically by
'usbmount'.

As I said, I'm using 'usbmount' so I should not mount it manually, right?

Maybe I didn't mentioned before: I purged nautilus and as many as I
could Unity's stuff. So, when I plug it in, it is automounted because I
have now installed usbmount.

But, only root can acces the USB drive, however /media/usb0 as a
mountpoint has permissions root:floppy and my username is in hte
'floppy' group. Still I don't understand why can access the drive as
root only?

The usb drive is present in mtab as:
/dev/sdc1 /media/usb0 vfat
rw,noexec,nodev,sync,noatime,nodiratime,gid=25,dmask=0007,fmask=0117 0 0
