Figure 13. USB-6251 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.
