Summary: A very nice and compact scanner, IF it can work with your computer. The instructions hint at a problem by warning against connecting its USB-2 cable (through which it gets its power) via a hub. Their phone support is good, but two hours of walk-throughs did not get the thing to work. Diagnosis: I should update my laptop's BIOS. No, they should update their design. This device is too finicky to be useful.
Summary: I put 3 stars because customer service was very nice and he gave a very great service for 2 hours, although they still couldn't solve the problem. What they told me is this CanoScan LIDE 35 is not compatible with Windows XP... And I cannot do anything with this scanner.. What I worry about is the shipping fee when I need to send back to Amazon.
