We could. But the point I was trying to make is that USB drivers only create urbs very infrequently (on device insertion), so any speed benefits are quite limited (we don't really care about speed when initializing a device.) If drivers switch over to the way this patch does it, then the benefits would be much greater. thanks, greg k-h _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
