5*4882a593SmuzhiyunDescription:
6*4882a593Smuzhiyun                Write the CHID (16 space-separated hex octets) for this host controller.
7*4882a593Smuzhiyun                This starts the host controller, allowing it to accept connection from
8*4882a593Smuzhiyun                WUSB devices.
9*4882a593Smuzhiyun
10*4882a593Smuzhiyun                Set an all zero CHID to stop the host controller.

16*4882a593SmuzhiyunDescription:
17*4882a593Smuzhiyun                Devices that haven't sent a WUSB packet to the host
18*4882a593Smuzhiyun                within 'wusb_trust_timeout' ms are considered to have
19*4882a593Smuzhiyun                disconnected and are removed.  The default value of
20*4882a593Smuzhiyun                4000 ms is the value required by the WUSB
21*4882a593Smuzhiyun                specification.
22*4882a593Smuzhiyun
23*4882a593Smuzhiyun                Since this relates to security (specifically, the
24*4882a593Smuzhiyun                lifetime of PTKs and GTKs) it should not be changed
25*4882a593Smuzhiyun                from the default.

31*4882a593SmuzhiyunDescription:
32*4882a593Smuzhiyun                The maximum PHY rate to use for all connected devices.
33*4882a593Smuzhiyun                This is only of limited use for testing and
34*4882a593Smuzhiyun                development as the hardware's automatic rate
35*4882a593Smuzhiyun                adaptation is better then this simple control.
36*4882a593Smuzhiyun
37*4882a593Smuzhiyun                Refer to [ECMA-368] section 10.3.1.1 for the value to
38*4882a593Smuzhiyun                use.

44*4882a593SmuzhiyunDescription:
45*4882a593Smuzhiyun                The device notification time slot (DNTS) count and inverval in
46*4882a593Smuzhiyun                milliseconds that the WUSB host should use.  This controls how
47*4882a593Smuzhiyun                often the devices will have the opportunity to send
48*4882a593Smuzhiyun                notifications to the host.

54*4882a593SmuzhiyunDescription:
55*4882a593Smuzhiyun                The number of retries that the WUSB host should attempt
56*4882a593Smuzhiyun                before reporting an error for a bus transaction.  The range of
57*4882a593Smuzhiyun                valid values is [0..15], where 0 indicates infinite retries.
