  Unable to read USB filesystems with EFI Bios

Status in QEMU:

Bug description:
  Preamble and version:
  With respect to my fix for using USB devices as -hda mentioned in bug 1223467
  Using Qemu 1.6.0 with OVMF r11337-alpha (Qemu is built from Source, OVMF is 
pre built)

  qemu-system-i386.exe -m 1024 -hda \\.\PhysicalDrive1 -L ovmf-ia32

  The EFI Shell is able to detect the hda block device, report its capacity and 
  but it sees no files or directories on the device.

  Similar commands:
  I have also seen the same with 
  qemu-system-x86_64.exe -m 1024 -hda \\.\PhysicalDrive1 -L ovmf-ia32
  qemu-system-x86_64.exe -m 1024 -hda \\.\PhysicalDrive1 -L ovmf-x64

  I tried very small (500MB) and very large (32 GB) USB devices with no 
  I re-built several versions of Qemu in an identical build environment, and 
found that: 
  Qemu 1.2.2 and before, all the above commands work and the EFI boot loader is 
  Qemu 1.3.0-rc0 and after do not work and the USB device appears blank.
  I'm reporting the bug here and not with OVMF because older versions of Qemu 
with the same OVMF bios work perfectly. 

  In all cases using '-L pc-bios' works perfectly.
  In all cases using an image of the USB device works.
