BUF08821EVM-USB Hardware Overview

3.5 Connecting the USB Cable to the BUF08821EVM

Once power is connected, the USB cable must be connected to the USB_DIG_Platform, as shown in

Figure 7. Note that the BUF08821EVM-USB test board and the USB_DIG_Platform board must each be

powered on before connecting the USB cable. Typically, the computer will respond with a Found New

Hardware, USB Device pop-up dialog. The pop-up window typically changes to Found New Hardware,

USB Human Interface Device. This pop-up indicates that the device is ready to be used. The

USB_DIG_Platform uses the human interface device drivers that are part of the Microsoft

Windows

operating system.

In some cases, the Windows Add Hardware Wizard may pop up. If this prompt appears, allow the system

device manager to install the human interface drivers by clicking Yes when requested to install drivers.

Windows will confirm installation of the drivers with the message shown in Figure 8.
