Accessing USB

[john wright]

I am trying to access a Human Interface device on USB. It is a device that
will lock the PC when you walk away. I read the article on Coding for fun
on MSDN and it was interesting, but as always it was C# with scant VB
details. What I am looking for would be a control that would communiate via
USB or classes I can import or set references to. I just want to poll the
device and lock the PC when someone walks away or the device is removed.
Can anyone point me to some classes or controls that would help in this
endevor. The Coding for fun article coded plugins, I just want a self
contained program to run.

And if any Microsoft people are listening, thank you for the port access in
2.0 framework, now how about putting in some USB support at least for
generic Human Interface Devices
