How can I use LabVIEW to refresh the USB port?

[HBM]

In my LabVIEW program I am using USB to communicate with some equipment. The USB connection might be a little unstable. Sometimes the LabVIEW program gets stoked and there is nothing I can do to make it running again. Only I can pull out the USB cable from the PC and then put it back in. Then LabVIEW is running again. How can I make this programmable / automatically?

Can you post your code? One way of handling it  checking for error and once you get any error then exit the while loop.

Here is a simple block diagram.

So you are not using any loop?

Have you considered Microsoft's 'devcon' command-line utility? You might be able to use it to refresh your devices. Try here: http://support.microsoft.com/kb/311272/EN-US/

Now I have tryed using a loop in LabVIEW, but it did not work.

Also I have tryed to use DevCon, but this did not work either. Not without rebooting the PC. See attached file.

Any other idea?
