Abstract: A control method, apparatus, and system capable of securely distributing a shared secret network encryption key from a host to a wireless peripheral device. The sharing of the secret network encryption key is accomplished without the intervention of a man-machine interface at the peripheral. Embodiments enable a wireless device to receive and store multiple encryption keys, to select the appropriate encryption key depending on the network in range of the device, and thus to freely associate with multiple networks.

Abstract: A polling method, apparatus, and system to detect the attachment and detachment of Universal Serial Bus devices in a wireless system. A hub provides a wired connection to the host and wireless attachment points for its devices, The host periodically queries the hub for changes in the hub's status register by sending a polling message through each of its wireless ports, and awaits a response. A peripheral device that wishes to attach to the system responds by sending its unique peripheral address. If a device currently occupies the port, the hub sends out the device's unique address in the polling message. If the device is still present, it responds by sending its unique peripheral address. If a response is not received after multiple retries, the device is considered detached. The hub thus determines the status of the ports and updates the status register, which is queried by the host.

Abstract: A polling method, apparatus, and system capable to detect the attachment and detachment of Universal Serial Bus (USB) devices in a wireless USB system. A USB hub provides a wired connection to the host, while providing wireless attachment points for its devices. The USB host periodically queries the hub looking for changes in the hub's status register. During each period, the hub sends a polling message through each of its wireless ports, and awaits a response. A peripheral device that wishes to attach to the system responds to the message by sending its unique peripheral address. If a device currently occupies the port, the hub sends out the device's unique assigned address as part of the polling message. If the device is still present, it responds by sending its unique peripheral address. If the host does not receive a response after multiple retries, the device is considered detached.
