enable/disable windows USB device

[Gjoraas]

Hi,

 I was wondering how I could disable/enable a device plugged into USB through LabVIEW.  I have Windows XP and the device managers shows the USB device working properly and it also has the option of enabling/disabling a device at the same time.  Is there a way that LabVIEW can do this type of function as well?

Thanks for the help,

I believe you cannot do this directly from LabVIEW. What I would do is to use a search engine to search if there is a Windows DLL that has access to this and then call that DLL from LabVIEW using the Call Library Function Node.

It is a windows tool called devcon that can help you. http://support.microsoft.com/kb/311272

You can run it with the "System Exec VI" Owning Palette: Libraries & Executables VIs and Functions
