B. CanoScan FB630U/FB636U

1. Outline

CanoScan FB630U/FB636U is not equipped with the CPU and the scanner is controlled by

the device driver installed in the host computer. The device driver includes the scanner control
program, which sets a command directly to the gate array register to control the scanner.

2. Outline of USB

CanoScan FB630U/FB636U is connected to the host computer via USB interface.
USB (Universal Serial Bus) is the next generation general-purpose input-output interface to

connect the computer peripheral devices.
1) Features of USB include;
* Connects peripheral devices to a computer.
* Connects up to 127 devices by a tree structure.
* Connects by 12 Mbps of "full speed mode" or 1.5 Mbps of "low speed mode". CanoScan

FB630U/FB636U is conforming to "full speed mode".

* Supports hot plug (able to connect/disconnect with the power ON).

2) Connection to USB devices

USB devices are connected to a host computer by a tree structure consisting of device

called "node" and "hub" which is a group of "node" as shown in Figure 2-33. The tree
structure has the following conditions.
* Able to connect up to 127 "node" and "hub" in total.
* Limited up to 6 layers.
* USB cable must be 5 meters or shorter.
