• Standard-A connector—Connects USB devices directly to a host or to the downstream port of a
hub.
• Standard-B connector—Allows device vendors to provide a standard detachable cable to
implement the switch-over between the two types of connectors.
Both types of connectors provide plugs and receptacles:
• Use an A-type receptacle with an A-type plug. An A-type receptacle is usually on a host or a hub
and functions as the output of the host system or hub system. An A-type plug usually connects to its
corresponding A-type receptacle on a host or a hub.
• Use a B-type receptacle with a B-type plug. A B-type receptacle usually functions as the input of a
device. A B-type plug usually connects to its corresponding B-type receptacle on a device.

The differences between the two types of connectors make sure you can correctly connect USB cables.
In Figure 59, a standar
d detachable USB cable specified in the USB protocols is needed. One end of the
cable must be an A-type plug, and the other end of the cable must be a B-type plug:
• The A-type plug of the cable is plugged in the A-type receptacle on the host.
• The B-type plug of the cable is installed in the B-type receptacle on the router.
Connecting the router and the host
To connect the router to a host, enable the USB device port of the router and then use a USB cable to
connect a host to the port. When you do so for the first time, the Windows operating system might ask
whether you want to install the driver. Because the Windows XP operating system supports the USB mass
storage medium, you can use the automatic installation function in the Hardware Update Wizard to
search and install the driver. After the installation, open the My Computer folder and you can see the
Removable Disk icon. Meantime, the LED of the USB device port on the router is on and the router can
be used as a USB mass storage medium.
