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.

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.

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.
