A method of and apparatus for communicating between a host and an agent. The method includes the step of performing a first transaction between a host controller and a hub. The hub is operable to perform a single transaction with an agent based on the first transaction. The method then includes the step of performing a second transaction between the host controller and the hub. The second transaction is based on the single transaction.

A method may be performed by a USB controller. The method may include retrieving a plurality of descriptors from a plurality of USB devices coupled to the USB controller. Each of the plurality of USB devices may be associated with at least one descriptor of the plurality of descriptors. The method may further include modifying at least one descriptor of the plurality of descriptors, and generating a first virtual USB device based at least in part on modifying the at least one descriptor. The method may also include outputting a first address associated with the first virtual USB device to a computing device.

An example apparatus may include a hub and a control unit. The hub may include a first input/output (I/O) connection, a second I/O connection, and a third I/O connection. The first I/O connection may connect to a peripheral device of a video conferencing system, the second I/O connection may connect to a first conferencing application, and the third I/O connection may connect to a second conferencing application via a video conferencing controller connected to the third I/O connection. The control unit may reconfigure the hub to change a connection of the peripheral device from the first conferencing application to the second conferencing application. The control unit may reconfigure the hub based on a location of a computing, wherein the second conferencing application is executed on the computing device.

A hub device is provided. An upstream-facing port (UFP) is coupled to a host device. A downstream-facing port (DFP) is coupled to a peripheral device. A control chip is coupled to the UFP, the DFP, and a memory, and includes a first transceiver interface, a second transceiver interface, a first processing circuit, and a second processing circuit. The first transceiver interface is coupled to the UFP. The second transceiver interface is coupled to the DFP. The first processing circuit is coupled to the first and second transceiver interfaces so that the host device communicates with the peripheral device. The second processing circuit is coupled between the first processing circuit and the memory. In response to the first processing circuit receiving an access command from the host device via the first transceiver interface, the first processing circuit triggers the second processing circuit to access the memory.
