NOTE
• Most USB-compatible computers have 2 USB ports. Other devices, such as keyboards, may
be equipped with an additional USB port. The scanner may be connected to any of these
ports.
WARNING
• Please note that some USB hubs will only function correctly if they are directly connected
to a USB port on the computer.
• The CanoScan FB630U/FB636U draws its power via the USB cable. Accordingly, a self-powered
USB hub is required if you are using a hub and other USB devices are going to be connected
simultaneously with the scanner.
