I have received the card reader i bought the other day, and the description says it supports mmc cards.  well, its only about 3 to 5 inches or so long, no usb cables came with it, which it is an external, usb interface, however it looks to me like it would fit in a usb slot, either end of it, the door toward the front, on the top opens but it doesn't seem to me like an mmc card would even fit, a simm chip might but i don't think an mmc would.  any clue what i got and/or any advice on how to connect and run this thing?
i knew card readers were fairly small, but i wasn't expecting it this small
