Abstract
A universal serial bus (USB) hub includes an upstream port configured to be communicatively coupled to a USB host, a downstream port, and a USB hub core circuit. The circuit is configured to determine a detachment from the downstream port, determine whether a USB element has reattached to the downstream port in USB mode, and, based on a determination that the USB element has reattached to the downstream port in USB host mode, perform USB multi-host bridging for the USB host and the USB element.
