| 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. |

| 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. |
