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 OEM
x .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
OEM x _original.inf in a different location.

NI USB-621x OEM User Guide 10 ni.com
2. Edit the device INF file by opening OEM x .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 621
x (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.
