Relying on sub-10ms response times in userspace is broken by design. I have written a driver with similar timing requirements, and I have done it in the kernel. This is the right way to go. Nothing else. regards Wolfgang -- Das Leben kann nur rückwärts verstanden, muß aber vorwärts gelebt werden. ------------------------------------------------------------------------- Using Tomcat but need to do more?
