ASP.NET/Silverlight Control USB Device

Question

I want to alert a user of a new message using some kind of USB device (e.g. a flashing light). Is it possible to control a USB device from ASP.NET or Silverlight?

Answer 1

You could possibly do this using a custom ActiveX component and som javascript in your webpage.

Alternatively you could use a Silverlight 4 application running in out-of-browser mode, but that is probably not what you want. SL4 can access locally installed Com components it is is running in out-of-browser mode, so in that case this should be realtively easy to do.
