5. Delete the EZUSB.SYS file.
6. Reinstall your Ocean Optics application and reboot the system when prompted.

The system is now able to locate and install the correct drivers for the USB device.
Mac Operating Systems
Since there are no device files for the NIR Spectrometer in a Mac operating system, you should not
encounter any problems if you installed the spectrometer before the SpectraSuite software.
Linux Operating Systems
For Linux operating systems, all you need to do is install the SpectraSuite software, then unplug and
replug in the spectrometer. Technically, the driver files for Linux simply give nonprivileged users
permission to use newly connected hardware. There isn’t any long-term harm to plugging in the device
before installing the software.
