What: /sys/class/usb_host/usb_hostN/wusb_chid

KernelVersion: 2.6.27

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/usb_host/usb_hostN/wusb_trust_timeout

|
|
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.
