这段代码展示了如何在Java中解析USB设备的类类型，特别是`UsbConstants.USB_CLASS_HID`，对应于人机交互设备（HID）。函数`nameForClass`通过switch-case结构返回不同USB类别的名称，当类别为HID时，返回的字符串是"Human Interface Device"。
public static String nameForClass(int classType) {
switch (classType) {
case UsbConstants.USB_CLASS_APP_SPEC:
return String.format("Application Specific 0x%02x", classType);
case UsbConstants.USB_CLASS_AUDIO:
return "Audio";
case UsbConstants.USB_CLASS_CDC_DATA:
return "CDC Control";
case UsbConstants.USB_CLASS_COMM:
return "Communications";
case UsbConstants.USB_CLASS_CONTENT_SEC:
return "Content Security";
case UsbConstants.USB_CLASS_CSCID:
return "Content Smart Card";
case UsbConstants.USB_CLASS_HID:
return "Human Interface Device";
case UsbConstants.USB_CLASS_HUB:
return "Hub";
case UsbConstants.USB_CLASS_MASS_STORAGE:
return "Mass Storage";
case UsbConstants.USB_CLASS_MISC:
return "Wireless Miscellaneous";
case UsbConstants.USB_CLASS_PER_INTERFACE:
return "(Defined Per Interface)";
case UsbConstants.USB_CLASS_PHYSICA:
return "Physical";
case UsbConstants.USB_CLASS_PRINTER:
return "Printer";
case UsbConstants.USB_CLASS_STILL_IMAGE:
return "Still Image";
case UsbConstants.USB_CLASS_VENDOR_SPEC:
return String.format("Vendor Specific 0x%02x", classType);
case UsbConstants.USB_CLASS_VIDEO:
return "Video";
case UsbConstants.USB_CLASS_WIRELESS_CONTROLLER:
return "Wireless Controller";
default:
return String.format("0x%02x", classType);
}
}
