The name says it all. I have this hp scanjet 3300C (usb) hooked up to my machine and it won't work. I've done just about every install and update from hp.com i could find. I'm leaning more towards the USB is malfunctioning because when you plug in the usb cable to this machine (with the scanner's power connected and on) it should find new hardware...right? what's the deal? thanks for the help!!!
