I was quite happily using Debian 7.2 with everything working and then, like every time I install Debian, I decide I need a newer package and break out testing and unstable and use apt pinning.
This always does a little bit of damage. After doing various packages and upgrades, I could no longer mount USB sticks as Read Write (RW), only Read Only (RO).
I’m not sure what causes this, but I think it’s to do with newer methods of handling mounting by FUSE. Just edit your /etc/fstab and comment out the USB lines:
#/dev/sdb1 /media/usb0 auto rw,user,noauto 0 0
#/dev/sdb2 /media/usb1 auto rw,user,noauto 0 0
Voila, your USB sticks will now remount in Read Write mode.
