Abstract:
Disclosed is a control method, which is used to control a USB system (10). The USB system (10) comprises an embedded circuit (11), a USB controller (12) and multiple interfaces (13), wherein the embedded circuit (11) comprises a switching circuit (112); and the switching circuit (112) is connected to the multiple interfaces (13). The control method comprises the following steps: (S11) polling multiple interfaces to determine a device access state of the multiple interfaces; and (S12) when it is determined that there is a device accessing one of the multiple of interfaces, using a switching circuit to establish a link between a USB controller and the interface. In addition, further disclosed are a USB system (10) and an electronic apparatus (100).
