Starting in August 2009, Vision Acquisition Software officially supports DirectShow imaging devices as part of the IMAQdx driver. You may download the driver at the following location: Vision Acquisition Software 2009

NI-IMAQ for USB Cameras driver software allows users to configure any DirectShow imaging device and acquire images into LabVIEW. Devices that  support this feature include USB cameras, webcams, microscopes, scanners, and many consumer-grade imaging products. 

Students and academic professionals can use this software with the NI Vision Development Module (included in the LabVIEW Student Edition) to analyze images with the aid of functions for image processing, including filters, binary morphology, pattern matching, and color inspection. The NI Vision Development Module also includes Vision Assistant for prototyping different functions, benchmarking inspections, and automatically generating code.

With NI-IMAQ for USB Cameras, you can:
- Acquire images from any USB imaging device with DirectShow support
- Select One-Shot or Continuous Image Acquisition modes
- Configure cameras programmatically, including the ability to programmatically select video modes
- Acquire directly into Vision Assistant for easy application prototyping
- Use the USB Express VI to quickly acquire images

Note: Although NI-IMAQ for USB Cameras comes with  documentation, it is not officially supported by the National Instruments Corp.

System Requirements:
- Windows Microsoft Windows Vista/Vista x64/XP/2000  (English, Italian, Japanese, French, Italian, Norwegian, Dutch, Spanish/Portuguese, Russian, or simple Chinese).

- NI Vision Acquisition Software 7.1 or later, for USB LabVIEW support.

error imaq for usb cameras - Jan 15, 2016

Installation Error You must have vision 7.1 or higher with LabVIEW 7.0 or higher, or you must have Vission Assistant 7.0 or higher installed to use this add-on I have labview 8.5 and vission assistant 8.0 , and I don't understand the generated error.

Handling the DLLs - Jun 5, 2015

Also, when you have successfully unpacked the installer, you should probably register both dlls after you placed them in the system32 folder. To do that open the cmd-window, go to where the dlls are (cd C:\windows\system32) and type regsvr32 dllname.dll in the cmd interface. You also might have to update the Call Library Function Nodes in all the IMAQ USB VIs in the imaqUSB.llb. Just open the VIs, view the Block Diagram (ctrl+e) and double-click the Call Library Function Node. Then put in the location (system32) of the desired dll-file. Restart LabView.

Use Universal Extractor to install the Package for LabVIEW 2009 and higher - Jun 5, 2015

The problem with this installer is, that it only has paths for LV Versions up to 8.6. Newer Versions will not be found and therefore the files are not installed. This is I think due to the already inbuilt USB module since LV 2009, where the IMAQ USB would not be necessary anymore. However, if you want to use old VIs that need VIs from the imaqUSB.lbb, you might have a problem. If the manual extraction described below via the command line interface fails to work, like in my case, you can use the tool "universal extractor" found here: Just extract the installer somewhere and then copy or move the needed files to the right places. The extracted folder structure and folder names should tell you where.
