Don't push 'answer' to reiterate your question. I'm not sure how it's possible that someone doesn't know what a pen drive is.

you will need to write an ActiveX control in C++, or perhaps in .NET if yuo're sure your users have .NET installed, ASP.NET cannot do what you want. The closest you can do, is ask your users to manually upload the file from their pen drive.
