You need to pass the device, not the partition.

If you don't even see the USB hard disk when booting up, then it
probably isn't formatted with GPT. Use --format on /dev/sdb.

If it shows up but ends up booting another OS, then your
EFI/boot/boot*.conf isn't updated, and you might have hit:

Let me know if the patch works.

And as Peter's mentioned, if your device supports x86_64, you need an
x86_64 image, and the same for 32-bit.

Note that I'm not sure how those are generated, but you should be able
to boot a 32-bit distro as long as you have a bootx64.conf and
bootx64.efi in /EFI/boot on the USB key.
