Abstract:
A USB hub includes an upstream port; a first USB device control unit for performing packet format conversion; an FIFO circuit for storing data outputted from the first host; a second USB device control unit for performing packet format conversion; and a plurality of downstream ports. When any one of the downstream ports is coupled to the mobile device, if the first host commands the mobile device to switch to a host role from a device role, the mobile device temporarily disconnects from the USB hub, and the first host commands the USB hub to change an internal routing path. After the mobile device switches to the host role, the first host still performs the host role, and the first USB device control unit performs the device role; the mobile device performs the host role, and the second USB device control unit performs the device role.

Claim (Index 8):
A universal serial bus (USB) hub, comprising:\n an upstream port coupled to a first host; a hub function module coupled to the upstream port for performing a hub function; a hos-to-host function module coupled to the upstream port, wherein when the mobile device connected to the USB hub performs the device role, under the control of the hub function module, signals are transmitted between the first host and the mobile device flows via a bypass path or the hos-to-host function module, which realizes a \u201chos-to-host mode\u201d; at least one control module coupled to the upstream port for controlling at least one device connected to the at least one control module; a virtual hub function unit coupled to the hub function module, the hos-to-host function module and the at least one control module, wherein the virtual hub function unit supports a virtual hub function and stores a plurality of USB addresses, and has a function of storing the relationship between the USB address and relevant devices; and a plurality of downstream ports coupled to the second USB device control unit, the virtual hub function unit specifies respective virtual USB address of the hub function module, the hos-to-host function module and the at least one control module according to a USB address specified by the first host.
