It definately isn't USB1 that is causing the problems... it's the person who told you that. it is that the Scanner is drawing too much power (I'm assuming that it doesn't have a power adapter of some sort?) Try plugging it into a POWERED Usb hub, should fix the problem right then and there. I've had that happen many times, and adding a powered hub has always fixed it because the device just needs more power, and Scotty's already giving it all it's got.
