  • Publication number: 20090286489
    Abstract: Methods and apparatus are provided for communicating between a host and a peripheral. In one embodiment, a method comprises the steps: establishing, in a manner transparent to the host, a wireless data link between a wireless hub device and a wireless peripheral device coupled to the peripheral, the wireless hub device coupled to and configured to communicate with the host, wherein the host is configured to communicate with peripheral devices over a wireline link at a plurality of data rates when connected via the wireline link; and controlling a flow of data between the host and the wireless hub device so that the host is unaware of the wireless data link, wherein the data is to be communicated between the host and the peripheral.

  • Patent number: 7310424
    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.

  • Patent number: 7149834
    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.

  • Publication number: 20030086388
    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.
