I just bought a psp and a 1gb memory stick to go with it, i was looking to put some pics and stuff on it using my macbook pro but to my surprise the thing wont even show up on the desktop when i plug it in!! ive tried it on my old emac and old iMac and it works perfectly fine! ...and the usb ports on the mb pro work fine with anything else but it seems like they dont even detect the psp?!?!? can someone help me out? do i need to download drivers or something for the PSP to work?!?!
