I have a question: Can i Access with DirectKS to the generic USB Driver on Windows XP? What do you mean by "the generic USB driver"? There's really no such thing on Windows. The answer to your question is "no". DirectKS allows you to communicate with kernel streaming drivers, which are used for multimedia devices, like streaming video cameras, encoders, and audio devices. It cannot be used to communicate with other WDM drivers. -- Tim Roberts, timr@xxxxxxxxx Providenza & Boekelheide, Inc.
