You can use System.Windows.Forms.SystemInformation.MousePresen t to check for the presence of the mouse

Using System.Windows.Forms.SystemInformation.MousePresen t I get a true or
false saying the mouse is installed or not, but it does not detect it. If i
unplugg the mouse it keeps telling its installed.

That I would assume is because for the OS, the mouse is still available. I think if finds out the mouse is not there only when you reboot. I suspect this may not be the case for a USB mouse, as the OS should be able to detect unplugging of a USB device.

That's a low-level issue not handled by VB.Net or the .Net Framework. You
might find something in the MSDN library.

Hi Perquiaga,

I think that the mouse can only be tested if it is working with tracking the
mouse move event.

However just an idea.

Any idea for re detect devices ?
Maybe could refresh the mouse status
