NOTE Ampro does not recommend connecting a USB boot device to the
LittleBoard 550 through an external hub. Instead, connect the USB
boot device directly to the LittleBoard 550.

when [USB HDD] is set as the drive option. This includes various
storage media types, such as USB hard disk drives, USB CD-ROMs,
CompactFlash™ cards, Secure Digital Memory Card™, and Flash or
