2014-07-28	418add6 Browse files » USB: improve error paths and tear-down ... USB core isn't too strict about allocation/deallocation and add/remove sequences of usb devices. Especially, error paths and device tear-down are kind of broken and cause hangs on failing usb device detect. This patch improves the situation by introducing a usb_free_device() that tears down allocated resources by usb_alloc_new_device(). usb_remove_device() now only deals with resources that have been added by usb_new_device(). Also, error handling is fixed or improved to ensure that no devices are unregistered that have not been previously registered.

While copying PortPowerCtrlMask it erroneously overwrites DeviceRemovable due to a copy-and-paste error. Fix it up.

Split this up and configure the hub only once and scan the ports during detect() time. This allows to plug in additional devices into a hub while continuing to use the already existing devices.
