host in each of these examples, the system is called a single master system.
Today, printers and digital cameras are also equipped with USB, not just the PC.
These devices can transfer data between themselves without going through a host PC using a
hosting function called USB Mini-Host.
The MB91F662 installed on this board is equipped with the Mini-Host function.
3. Signal lines
USB cables are inexpensive to make, using only two signal lines and two power lines.
The two signal lines carry 3.3 V differential signals (D+ and D-). The two power lines are
labeled Vbus (5V), and GND. Connected devices can draw up to 500 mA of power, allowing
manufacturers to develop devices that do not require external power supplies.
(This board can supply power from the USB.)
Plug types are discussed in Section 4.4.

Connection formats
The three functions explained here form a USB system.
<Host>
PCs are equipped with the host function as shown in Figure 4.3-1.
The number of devices (or functions), including the hub, that can be connected to a single host
is 127. (The hub is treated as a function.)
<Hub>
The hub is used mainly to increase the number of ports. With PCs, some monitors and
keyboards are equipped with USB hubs.
<Function>
Functions are provided on the peripheral. In a PC, the keyboard and mouse are functions.
The host and function are connected in a so-called star topology, which means simply that
functions are directly connected to the host via a hub for communicating on a 1:1 basis.
