Hi all,
I am having ocean optics usb 4000 spectrometer. I want to acquire its data in LabVIEW. For this application, I downloaded the instrument driver from NI Site (http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=7833BD4A31DA1274E04400144FB7D21D). I copied the project into instr.lib directory and installed driver using Ocean Optics USB4000_vista.inf file as instructed in the installation instructions then I restart my PC and connect the spectrometer and windows was successfully able to install driver for my spectrometer and I was able to run the example VI as well. But next day when I tried to connect the same device, windows was not able to install the driver and showed the message "Driver not successfully installed". I tried to update the driver software from the device manager but it shows "Windows was not able to install your Unknown Device" then I uninstall the driver and reinstall it but still got the same error.
I am using LabVIEW 2012 (32 bit) on windows 7 64 bit system.
Please help.
