Device. Click the OK button to confirm the device removal.

The system should now be able to locate and install the correct drivers for the USB device.

Apple Mac OSX Operating Systems

Since there are no device files for the QE Pro Spectrometer in a Mac operating system, you should not encounter any problems if you installed the spectrometer before the operating software.

Linux Operating Systems

For Linux operating systems, all you need to do is install the 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.
