所述主控芯片内置有HID设备描述符。
主机控制器设备驱动程序读取的设备描述符包含关于设备的信息，例如class、subclass和protocol。
The device descriptor read by the host controller driver contains information about the device, such as class, subclass, and protocol.
因为在枚举期间从适配器读取的设备描述符与hci_usb驱动程序注册到usb核心的信息相匹配，所以这个驱动程序可附加到Belkin usb设备。
Because the device descriptor read from the adapter during enumeration matches the information registered by the hci_usb driver with the usb core, this driver gets attached to the Belkin usb device.
