<p>Systems and methods of device identifier selection are disclosed. In a particular embodiment, a method includes, at a hub device having a plurality of ports including a first port, a second port, and a third port, receiving a first message from a host device. The first message including a broadcast indicator. The method also includes, in response to determining that the first message requests enumeration, emulating a ring communication topology by serially propagating messages including an enumeration indicator to a first device via the first port and to a second device via the second port. The method further includes, in response to determining that the first message does not request enumeration, selectively sending the first message to the first device substantial6y concurrently with sending the first message to the second device. Emulating the ring communication topology enables the hub device to provide a first distinctive identifier value of the first device and a second distinctive identifier value of the second device to the host device.</p> |
