I have the 300e, and unfortunately you can't hook it up to the computer with a USB cord. You have to buy a special memory card and adapter. Hancock's doesn't sell them, I bought mine online but they were pretty cheap. It's a compact flash adapter (ATA PC) and memory card, and your computer has to have a flash card slot. Google "janome 300e card adapter" - there is a really good PDF tutorial by Jolie Fribley that should come up during your search. Hope this helps!!
