You need a device that can work like a USB gadget that runs Linux.  That
should narrow the choices down greatly :)

Or you can get a pci card that acts like a USB gadget and work from
there.

Then just pick a usb gadget type that isn't already implemented.  Or
rewrite one of the existing gadget types, it's up to you.
