Modifying the USB Device Name in Microsoft Windows

You can change how the USB-621x OEM device name appears when users install the device in both the Found New Hardware Wizard that appears when the device is initially installed and in the Windows Device Manager.

Windows Vista/XP Users
Figure 9 depicts how a USB-6211 (OEM) device name appears in the Found New Hardware Wizard and Windows Device Manager.

Figure 9. USB-6211 OEM Device in the Found New Hardware Wizard and Device Manager (Windows Vista/XP)
To modify the device name in the Found New Hardware Wizard and Windows Device Manager in Microsoft Windows Vista/XP, complete the following steps.

Note You must have NI-DAQmx 8.6 or later installed on your PC.

1. Locate the OEMx.inf file in the y:\WINDOWS\inf\ directory, where x is the random number assigned to the INF file by Windows, and y:\is the root directory where Windows is installed.
   Note New security updates to Microsoft Vista and NI-DAQ 8.6 create random INF files for NI hardware. Windows assigns random file numbers to all INF files, which causes the user to search through several INF files until the correct file is located.
   If you want to revert back, save a copy of this file as OEMx_original.inf in a different location.

2. Edit the device INF file by opening OEMx.inf with a text editor. At the bottom of this file are the descriptors where Windows looks to identify the device. Locate the two lines of text that contain in quotes the descriptors for the device name you are modifying. Change the descriptor on both lines to the new device name, as shown in Figure 10.
   
   Figure 10. INF File Descriptors Changed to “My Device” (Windows Vista/XP)

3. Save and close the INF file.

4. Go to the Windows Device Manager.
   (Windows Vista) In the Device Manager, notice that the OEM device now appears as My Device, as shown in Figure 11.
   (Windows XP) In the Device Manager, right-click the OEM device under Data Acquisition Devices, and select Uninstall. Disconnect the USB cable from your PC.

When you reconnect the device, it appears as My Device in the Found New Hardware Wizard and Windows Device Manager, as shown in Figure 11.

Note When the device is initially installed, the Windows alert message may display the following: Found New Hardware: M Series USB 621x (OEM). This message appears for a few seconds until the custom name appears and the Found New Hardware Wizard is launched. This alert message device name cannot be changed.
