| 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. |
