I need to develop a web application that needs communication with a hardware device connected the the client computer via USB. What possibilities do I have using Intraweb/Delphi (Windows only).

in most cases, a web application can not access the hardware of a client's browser (for a webapp, the web browser is actually like the OS is for a desktop app)
so there are times where i think the best solution is to use a service or a small util app in the client's machine, that will connect to your hardware, and make the webapp and this util "talk" between them, instead of talking directly with the hardware.

but that also depends on the hardware.
for example : CGDevTools have a component to use a WebCam in you iw app.

what do you want to connect?

As mentioned by Eitan, browsers won't give you direct access to hardware from HTML or JavaScript. This is valid for any web application (unless you use something like Flash, for instance).
