Title:
  USB disks with VFAT are not mountable in saucy

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I have two USB disk devices that don't work anymore when I updated to
  Saucy.

  The first is a plain USB stick, which prints this into dmesg:

  [26938.517257] sd 7:0:0:0: [sdd] 7928832 512-byte logical blocks: (4.05 GB/3.78 GiB)

  The second is an Android phone, which prints this to dmesg:

  [27181.559355] FAT-fs (sdd1): unable to read boot sector to mark fs as dirty

  Both devices:

  - work on other machines
  - fail when plugged to a hub or directly in the computer

  A USB disk with ext4 works flawlessly.
