The default value of 20 4000 ms is the value required by the WUSB 21 specification. 22 23 Since this relates to security (specifically, the 24 lifetime of PTKs and GTKs) it should not be changed 25 from the default. 26 27What: /sys/class/uwb_rc/uwbN/wusbhc/wusb_phy_rate 28Date: August 2009 29KernelVersion: 2.6.32 30Contact: David Vrabel <david.vrabel@csr.com> 31Description: 32 The maximum PHY rate to use for all connected devices. 33 This is only of limited use for testing and 34 development as the hardware's automatic rate 35 adaptation is better then this simple control. 36 37 Refer to [ECMA-368] section 10.3.1.1 for the value to 38 use. 39 40What: /sys/class/uwb_rc/uwbN/wusbhc/wusb_dnts 41Date: June 2013 42KernelVersion: 3.11 43Contact: Thomas Pugliese <thomas.pugliese@gmail.com> 44Description: 45 The device notification time slot (DNTS) count and inverval in 46 milliseconds that the WUSB host should use. This controls how 47 often the devices will have the opportunity to send 48 notifications to the host. 49 50What: /sys/class/uwb_rc/uwbN/wusbhc/wusb_retry_count 51Date: June 2013 52KernelVersion: 3.11 53Contact: Thomas Pugliese <thomas.pugliese@gmail.com> 54Description: 55 The number of retries that the WUSB host should attempt 56 before reporting an error for a bus transaction. The range of 57 valid values is [0..15], where 0 indicates infinite retries. 58
