What: /sys/class/uwb_rc/uwbN/wusbhc/wusb_chid Date: July 2008 KernelVersion: 2.6.27 Contact: David Vrabel 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/uwb_rc/uwbN/wusbhc/wusb_trust_timeout Date: July 2008 KernelVersion: 2.6.27 Contact: David Vrabel 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. What: /sys/class/uwb_rc/uwbN/wusbhc/wusb_phy_rate Date: August 2009 KernelVersion: 2.6.32 Contact: David Vrabel Description: The maximum PHY rate to use for all connected devices. This is only of limited use for testing and development as the hardware's automatic rate adaptation is better then this simple control. Refer to [ECMA-368] section 10.3.1.1 for the value to use. What: /sys/class/uwb_rc/uwbN/wusbhc/wusb_dnts Date: June 2013 KernelVersion: 3.11 Contact: Thomas Pugliese Description: The device notification time slot (DNTS) count and inverval in milliseconds that the WUSB host should use. This controls how often the devices will have the opportunity to send notifications to the host. What: /sys/class/uwb_rc/uwbN/wusbhc/wusb_retry_count Date: June 2013 KernelVersion: 3.11 Contact: Thomas Pugliese Description: The number of retries that the WUSB host should attempt before reporting an error for a bus transaction. The range of valid values is [0..15], where 0 indicates infinite retries.
