Removing the line which mounted the USB device from /etc/fstab did the 

Used to be:
# External USB disk
/dev/sdc1       /mnt/usb        ext3    defaults        1       2
#LABEL=/mnt/usb   /mnt/usb      ext3    defaults        1       2
# External USB disk as LVM Volume '**new**'
/dev/<VOLUME_GROUP>/<LOGICAL_VOLUME_**new**>  /mount/point  ext3 
suid,dev,exec  0  2

Commenting the line
#/dev/sdc1       /mnt/usb        ext3    defaults        1       2

solved it! :)
