HUB的上行PORT面向HOST,下行PORT面向设备(HUB或功能设备)。在下行PORT上,HUB提供了设备连接检测和设备移除检测的能力,并给各下行PORT供电。HUB可以单独使能各下行PORT。不同PORT可以工作在不同的速度等级(高速/全速/低速)。 如果USB设备通过集线器和Host通信,主机集线器监视着每个端口的信号电压,当有新设备接入时便可觉...
如果usb的第i个port处于resume或reset状态,则hub中busy_bits中第i个位置1;如果busy_bits中第i个位置1,则退过当前port;event_bits中第0位用来表示hub本身是否产生local power status change和是否产生过流,其它的各位用来表示hub下各个port状态是否发生变化,这些状态包括: ConnectStatusChange 连接状态发生变化,PortEnab...
