1.2 Introduction
This section describes the connection and startup of the USB08
(universal serial bus) evaluation board demo application. The main
component of the USB08 is the Motorola MC68HC908JB8 8-bit
microcontroller (MCU).
1.3 Required System Configuration
To connect theUSB08, youwill needa personal computer (PC) withone
of the following Microsoft®operating systems:
•Windows®98
•Windows ME
•Windows 2000 Professional
NOTE: Ensure that the PC has the necessary hardware (universal serial bus
(USB) host controller and USB root hub) and that the necessary system
drivers are installed.

1.4 Connecting the Demo Board to the PC
Since low-speed USB devices should be equipped with a captive
connection, the USB cable is fixed on the USB08 board (downstream
direction). In the upstream direction (PC/host side), the USB
connections are alwaystypeA. Therefore, the cable oftheUSB08demo
board has a type A plug.
The connection ofthe demoboard is made directly to the USB socketof
the PC or, as shown in the Figure 1-1, to a USB hub.
Figure 1-1. Demo Board Connected to the USB Hub
The board supply current can be delivered by the USB connection.
Therefore, the jumper JP2, which is directly beside the USB cable, has
to be in the position Bus Powered. The jumper JP1-A (jumper block,
highest position) must be opened, which corresponds to the default
shipping configuration.

1.5 Driver Installation
Forthisexample,theinstallationofthedriversoftwareisdescribedusing
the Windows 2000 operating system. The installation using Windows 98
(second edition) looks quite similar.
After the electrical connection of the demo board, the Windows
operating system recognizes the presence of a new hardware
component and shows the message Found New Hardware.

The hardware assistant, Figure 1-3, now tries to find the suitable driver
information for the USB08 evaluation board. Click the Next button.
NOTE: The installation using the Windows 2000 operating system requires
administrator rights.
