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.
