All of a sudden, on ALL my XP's, when I plug in the camera I get errors USB device unknown. Tried reinstalling a few times, can't get it to be recognized either as the camera or just as a simple storage device. Tried reinstalling the driver from the CD, and still nothing. I have pictures on there I need to get off. I have a Windows7 laptop, and that just goes berserk if I try to attach it. Help!
