3. Delete the OOI_USB.INF in the INF directory. If your computer is running either the Windows
2000 or XP operating system, you must also delete the OOI_USB.PNF file in the INF directory.
4. Navigate to the Windows | System32 | Drivers directory.
5. Delete the EZUSB.SYS file.
6. Reinstall your Ocean Optics application and reboot the system when prompted.
7. Plug in the USB device.
The system is now able to locate and install the correct drivers for the USB device.
Older Version of OOIBase32 Installed
If the PC to be used to interface to your QE65000 already has an older version of OOIBase32 software
installed, you must install the latest version of OOIBase32. You can download the latest version of
OOIBase32 from the Software and Technical Resources CD or from the Ocean Optics website at
http://
www.oceanoptics.com/technical/softwaredownloads.asp.
You do not need to uninstall previous versions of OOIBase32 when upgrading to the latest version.
