Abstract: In one embodiment, provided is a method that includes detecting disconnect of a link at a Universal Serial Bus (USB) device coupled to a USB host via a USB bus, disconnecting the USB device from the USB bus, and modifying a power state of the USB device to a reduced power state. Disconnecting the USB device from the USB bus includes configuring the USB device such that the USB host recognizes the USB device as being disconnected from the USB bus. The reduced power state allows the USB device to monitor a status of the link such that the USB device is able to detect a reconnect of the link.

Abstract: A system for automatically switching peripheral connectivity between two host devices based on respective connectivity of the hosts. The method may be used where peripherals are usually attached to one host and are automatically switched to a second host when the second host is attached to the system. A USB switching hub may be operable to automatically switch connectivity of the peripheral device(s) from the first host device to the second host device when the second host device is connected to the USB device. This automates the process for the end user when normally all peripherals are attached to one host, and some or all peripherals are shared with a second host when the second host is attached.

Abstract: In various embodiments, a wireless host and a wired host may communicate with downstream devices through a USB switching hub. A wireless host/wireless bridge may be temporarily physically coupled to an upstream port of the USB switching hub to complete association with another wireless bridge coupled to the USB switching hub as a downstream device through a downstream port. During association, the host and downstream wireless bridge may exchange an encryption key to be used for future wireless communications. After association, the wireless host may be disconnected from the USB switching hub to communicate remotely. In some embodiments, the wireless host may not need to be physically coupled to the USB switching hub during association.
