Erm, like doing a scan of a bus? With 15 devices to probe, you've increased the time from 15 * 3 = 45 seconds to 15 * 20 = 300 seconds. That's not cool ;-( Maybe we could default this in the transport or something so USB can override it. -- Matthew Wilcox Intel Open Source Technology Centre "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
