I have a problem with my Microtek Scanmaker i700, i'm using windows xp...when I plug the USB or a Firewire Connection to my Desktop computer it cannot detect my Scanmaker i700 scanner...I'm using the 6660 version of Scanmaker i700 whick I download it from the Internet. The scanmaker i700 software installed smoothly, but then again it cannot detect my scanner to my desktop computer. I already replaced the USB Cable and also 1394 cable...but still has a problem decting it
