How to install and run USB device application without NI-VISA environment?

[driver1999]

Hi everyone:
      I develop a LabWindows/CVI8.5 application that uses a driver for a USB device created using the NI-VISA 4.6.2. The application is ok when the NI-VISA  environment is installed in PC. But the  NI-VISA 4.6.2 is too big(326M).  Can be the USB device successfully installed in non-development machine without NI-VISA 4.6.2?  Just need some files, such as INF, NiViUsbK.sys and ni-visa32.dll, the device will be installed and run.   If the way is feasible, please tell me how to do. Which files are necessary to the device is installed in non-development machine without NI-VISA 4.6.2 environment? It is so big, I need a minimum NI-VISA system.
      I need your help.

Personally I use the open source LibUSB. It links without difficulty with
CVI. And it works both on Linux and Windows, which is a big plus. Haven't
touched it in 2 years though.
