Kubuntu automatically mount USB in /media/usb0 as read-only

Question

After a fresh install of Kubuntu 15.10, my USB drive is automatically mounted as read-only in /media/usb0 instead of /media/<username>/

Mount output

$ sudo mount
…
/dev/sdb1 on /media/usb0 type vfat (rw,nodev,noexec,noatime,nodiratime,sync,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)

Device is owned by root:

drwxr-xr-x  9 root root 4,0K janv.  1  1970 usb0/

dmesg | tail

I noticed errors=remount-ro at the end of the line of the mount result for the USB, so I decided to check dmesg for errors:

dmesg | tail
…

[64509.698730] FAT-fs (sdb1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

fsck

I run

$ sudo fsck.vfat -a /dev/sdb1
fsck.fat 3.0.28 (2015-05-16)

dmesg | tail again

…

No more errors, but still no write permissions.

Question

How do I automatically mount my USB a read-write?

Answer 1

1. I remove usbmount (that I installed earlier) ;

2. configure removable devices dialog (see KDE Plasma 5 Missing Removable Devices Option ):

   kcmshell4 device_automounter_kcm
   

3. Starting 'Removable Device Automounter' from the Service Manager using

   kcmshell4 kcmkded
   

4. unplug, replug and voilà!
