| What: /sys/class/usb_host/usb_hostN/wusb_trust_timeout |
| Date: July 2008 |
| KernelVersion: 2.6.27 |
| Contact: David Vrabel <david.vrabel@csr.com> |
| 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. |
