What:           /sys/class/usb_host/usb_hostN/wusb_chidDate:           July 2008KernelVersion:  2.6.27Contact:        David Vrabel <david.vrabel@csr.com>Description:                Write the CHID (16 space-separated hex octets) for this host controller.                This starts the host controller, allowing it to accept connection from                WUSB devices.                Set an all zero CHID to stop the host controller.What:           /sys/class/usb_host/usb_hostN/wusb_trust_timeoutDate:           July 2008KernelVersion:  2.6.27Contact:        David Vrabel <david.vrabel@csr.com>Description:                Devices that haven't sent a WUSB packet to the host                within 'wusb_trust_timeout' ms are considered to have                disconnected and are removed.  The default value of                4000 ms is the value required by the WUSB                specification.                Since this relates to security (specifically, the                lifetime of PTKs and GTKs) it should not be changed                from the default.
