USB devices block my Labview Program

[Intaris]

Sounds to me like you're blocking your event handler due to some system event. The fact thst you see a freeze after a keypress would support this.

But what he says is whenever he connects any usb device than it freezes.

[Intaris]

I'm fully aware of that. Without code we cannot know what is going on in the event loop (if anything). The freezing action sounds like an event structure problem. How the usb leads o this I cant say without code. It could be a trivial loop termination problem with the freeze as an unwanted side effect

Correct. But where is the problem facer buddy .we need to hear from him. May be he also doesnt know the problem or cause.

Thank you guys ..

The programs is block with some USB devices , not all , for example  an USB modem or the USB keyboard , ..

The USB modem block the program automatically , when the O.S detect the connection.

The USB keyboard , in other hand ,  only block the program in one case when I use some features in other programs ( not related with Labview at all ) and I need to push one key and move the mouse through an image ( to see the pixel amplitud for example ) I repeat this program is not related with Labview. If I do the same with and PS/2 key board , it does not  happen .

The problem is that I don't have access to the code , it is developed by a third party and they said , and it is true , that the system is working in other computers ( of course this is one of the first with windows 7 ).

And what is it that you can do about this?

I understand that the software is not changable for/by you and, on the other hand, you can do nothing about the hardware setup.

So what is it what you can do where we can help you with?

This is actually very difficult stage. better talk to the third party person and discuss the issue. He can surely help you as he may intentionally doing this.
