Hi list ! We use a fairly large usb tree with about 12 hubs and 18 high speed devices to build a control surface. With kernel 2.6.8.1 it took about 8 seconds from plugin of the first hub (where all other hubs/devices are connected) to the root hub until all hubs/devices where "found" and announced in "/var/log/messages". With kernel 2.6.15 this time increased to about 17seconds. That doubles the time we need to get our surface working. The distribution we use is a "self made" one, so in this test we only changed the kernel and the appropriate drivers. udev and the hotplug environment were the same in both cases.
This is perhaps a stupid question, but is there a possibility to speed up the connect handling (without rewriting the whole usb drivers ...) in the newer kernel ? Any hints are welcome.
