I've owned at least one computer (retired now) that would not boot from
a USB stick but would boot from a USB-connected CDROM or hard drive. I
have another computer (my main workstation) which will boot from USB
media even when disabled in the BIOS and last in the boot sequence. I
regularly come back to the machine and find a hung boot because I
forgot to remove a USB stick.
