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=7833BD4A31DA1274E04400144FB7D2... 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.
Solved! Go to Solution.

Hi,
Yes my problem has been solved. There was a problem in the EEPROM of the spectrometer. It was corrupted. So I reprogrammed the EEPROM and the problem is no more exist. Now my system is able to detect the device and data is also acquired using LabVIEW.
Thanks for your reply.

Hi,
I encountered the same problem of "unknown device" after reconnecing the USB4000 to the computer. How did you reprogrammed the EEPROM?
Thanks a lot.
