如何使用nodejs从USB读取数据

npm install usb

const usb = require('usb');

const devices = usb.getDeviceList();
const targetVendorId = 0x1234; // 目标设备的供应商ID
const targetProductId = 0x5678; // 目标设备的产品ID

let targetDevice = null;

devices.forEach(device => {
  if (device.deviceDescriptor.idVendor === targetVendorId && device.deviceDescriptor.idProduct === targetProductId) {
    targetDevice = device;
    return;
  }
});

if (!targetDevice) {
  console.log('未找到目标USB设备');
  return;
}

targetDevice.open();

const interface = targetDevice.interfaces[0];
interface.claim();

const inputEndpoint = interface.endpoints[0];

inputEndpoint.transfer(64, (error, data) => {
  if (error) {
    console.error('读取数据时发生错误', error);
    return;
  }

  console.log('读取到的数据：', data);
});
