5 Description:
6                 Write the CHID (16 space-separated hex octets) for this host controller.
7                 This starts the host controller, allowing it to accept connection from
8                 WUSB devices.
9
10                 Set an all zero CHID to stop the host controller.

12 What:           /sys/class/uwb_rc/uwbN/wusbhc/wusb_trust_timeout

16 Description:
17                 Devices that haven't sent a WUSB packet to the host
18                 within 'wusb_trust_timeout' ms are considered to have
19                 disconnected and are removed.  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.

27 What:           /sys/class/uwb_rc/uwbN/wusbhc/wusb_phy_rate
28 Date:           August 2009

30 Contact:        David Vrabel <david.vrabel@csr.com>
31 Description:
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.
