From: Savageaggie on 24 Feb 2006 15:10 Joel, Thank you for writing in to us for support. The error you are receiving has to do with a compatability issue between the camera and the architecture of DirectShow, a multimedia driver on your PC which is what our USB software is built on. For more information on our USB software, please see the following link: - <a href="http://digital.ni.com/public.nsf/websearch/89E33B77CFE244E986256F8E004E0F13?OpenDocument" target="_blank">http://digital.ni.com/public.nsf/websearch/89E33B77CFE244E986256F8E004E0F13?OpenDocument</a> - <a href="http://digital.ni.com/public.nsf/websearch/274A74A901399D0486256F32007295F9?OpenDocument" target="_blank">http://digital.ni.com/public.nsf/websearch/274A74A901399D0486256F32007295F9?OpenDocument</a> Our NI-IMAQ for USB driver was released as a free tool for our customer to use with our Vision Development Module; however it was never intended to be developed into a full driver and is not currently supported or being developed by our R&D team. Please contact the camera manufacturer to resolve any compatibility issues with DirectShow. We apologize for any inconvenience this has caused you and your team. Thanks, Scott Savage - National Instruments

For one IMAQ for USB is unsupported software. This means someone at NI has probably spend some considerable privat time in developing this piece of software and wanted it to be available to potential users. But NI decided that this is not something they want to sell for money nor that they can justify doing support, improvements, quality control and full documentation when giving it away for free. The choices are then very simple: Either claim that there isn't something like this available and you have to look elsewhere or make it available with the big warning that it is unsupported and that if you are happy with it that is nice but if you have problems with it that there is no guarantee at all to get support in any form. Personally I think some of the AEs from NI already go out of their way by still answering questions about IMAQ for USB rather extensively and with quite a lot of technical understanding and they really deserve a big thanks for that, but trying to get more out of them is more likely to get IMAQ for USB completely pulled from the downloads than getting it to the standards of a real product, which by the way most probably won't be for free anymore. If IMAQ for USB doesn't work for you then you can always look for IVision at http://www.hytekautomation.com/Products/IVision.html or try to use some ActiveX control with DirectX camera support, though integrating an ActiveX control into LabVIEW for image acquisition isn't trivial at all and I would guess IVision would be a very good investment instead of trying to do your own ActiveX interface. You can download a trial version of IVision though to see if it works for you. Rolf Kalbermatter

This would at least for the original poster mean that he has a different problem. Rolf Kalbermatter
