HCD drivers are involved only so far as they contain an emulation of a hub known as the virtual root hub. Usbcore has helpers which lift part of that burden from the HCD drivers. Generally, the URB callback of the hub driver will be called and it'll queue an event for khubd, which will eventually call usb_new_device() HTH Oliver ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
