The iRiver H3xx models, at least, have a USB Host socket as well as a USB
Device socket. I have no idea whether the Host socket is currently supported
by Rockbox' USB stack, or how many other players have a similar arrangement,
but on these players the Original Firmware supports plugging in USB storage
devices and transferring files between the two "drives", although it's not
possible to play music directly from the "remote" drive.
