3.3 Installing the USB Drivers

The communication interface between the AFE44x0SPO2EVM board and PC is through the USB, using

the CDC profile. A one-time installation of the USB driver is required for the communication between the

AFE44x0SPO2EVM and PC application.

NOTE: For Windows 8, signed driver enforcement may have to be disabled. Section 3.3.1 explains

how to do this.

Following these steps ensures proper installation of the USB drivers:

1. Plugin the USB-to-mini USB cable to J4 of AFE44x0SPO2EVM and the other end to the USB port on

the PC.

2. Win XP OS starts up the New Hardware Wizard to enable the user to install the USB driver for the new

hardware. The Windows 7 or Windows 8 OS attempts to find the driver for the new hardware found

automatically and if the driver is not found, there is no pop-up message to indicate that the driver

installation failed. In the Windows 7 or Windows 8 OS, click on Device Manager, right click on

MSP430-USB example under Other devices and click on Update Driver Software as shown in

Figure 8. This step is not required for the Windows XP OS.
