Will a USB 2 scanner work on a USB 1.1 PC?

I'm interested in buying a Canon LiDE 20 scanner. However, it has a USB 2 interface while the computer I want it for has a USB 1.1. Will it work? Thanks.

Yes but only at USB1.1 speed

Cheers Bremner, much appreciated.

Yes it will. But the LiDE20 is only 1.1 anyway.

On Amazon it says on the LiDE 20 blurb: "USB 2.0 Full Speed interface, for single cable connection for both power and data transfer" - have they got it wrong?

Not quite. Canon have a different way of expressing their USB than the generally accepted way. The LiDe20 does have a USB2 interface, but works at a speed of USB1.1

Canon's definition is USB "full" speed = 1.1

USB "high" speed = 2.0
