I will work with a host sequencer audio/midi application. I will implement a plug-in that will have to capture audio from an external usb device when required (asked) by the host application. If my plug takes too much time to capture audio from usb it should be a big problem for the host application... it's right? thanks

the fact is that i need a less than 10 ms latency...
What do you mean by that? People always say they want extremely low latency, but I suspect most who do so are saying it because it was a bullet item on some marketing PowerPoint presentation, and not because it reflects any real technical requirement. What is your application?
Most digital cell phones have a latency of several hundred milliseconds, and it certainly has not slowed their path to world domination. For video conferencing, there's little point in aiming any lower than about 100 milliseconds, partly because a single video frame lasts 33ms, and partly because network latency swaps the local latency.
Is it possible with Directshow?
It's not impossible. It depends on what else is going on, and what you are doing with the data. I'd like to hear more about what your application is.
