How does bindings.get_device_usb_strings work?

bindings.get_device_usb_strings works by taking a single argument, which is a string representing the path to the HID device. The function then sends a USB control request to the HID device to retrieve information about the device, such as its vendor ID, product ID, and serial number. It then returns an object containing this information, as well as any other USB-related information that is available. The USB-related information returned by bindings.get_device_usb_strings can be useful when working with HID devices, such as game controllers or other input devices. By retrieving this information, you can identify the specific device that is connected to the computer and customize the behavior of your application accordingly. Note that bindings.get_device_usb_strings is typically used in conjunction with other HID-related functions, such as bindings.device(), which returns a device object that can be used to read and write data to the HID device.

const HID = require("node-hid");
const bindings = require("bindings")("node_hid_bindings");

// Find the first device that matches a specific vendor ID and product ID
const deviceInfo = HID.devices().find(
  (d) => d.vendorId === 0x1234 && d.productId === 0x5678
);

// If a matching device is found, retrieve its USB strings
if (deviceInfo) {
  const usbStrings = bindings.get_device_usb_strings(deviceInfo.path);

  console.log("Vendor ID:", usbStrings.vendorId);
  console.log("Product ID:", usbStrings.productId);
  console.log("Serial Number:", usbStrings.serialNumber);
}

In this example, we start by importing the node-hid library and the bindings library, which is used to access the get_device_usb_strings function. Next, we use the HID.devices() function to retrieve information about all of the HID devices that are currently connected to the computer. We then use the Array.find() method to find the first device that has a specific vendor ID and product ID. If a matching device is found, we call bindings.get_device_usb_strings() with the path to the device as an argument. The function returns an object that contains USB-related information about the device, such as its vendor ID, product ID, and serial number. Finally, we log the USB-related information to the console. The output shows the vendor ID, product ID, and serial number of the matching HID device, if one is found. Note that this is just an example, and the actual vendor ID, product ID, and serial number values will depend on the specific device that is connected to the computer.
