the picture shows a smartmouse/pheonix reader connected to an rs232-usb serial adaptor, then the lead vanishes under a flat cable, that looks like theres no header connection under it, alsothe card reader has no power source connected to it
after modifying many receivers with hard drives, card readers etc, id be inclined to say thats a fake m8, placed in the receiver to get people talking, as usb-232 adaptors need drivers
