我使用以下代码从使用其他软件（Zwift，它显示加密狗实际接收到的数据）的ANT +加密狗接收数据（使用OS X）：
/* Require the config */
require('dotenv').config()
/* require the usb class */
var usb = require('usb');
/* find the device */
var device = usb.findByIds(process.env.VENDOR_ID, process.env.PRODUCT_ID);
/* open the device */
device.open(true);
/* claim interface WHERE IS THIS FOR */
const [interface] = device.interfaces;
interface.claim();
/* Start Polling */
const [inEndpoint, outEndpoint] = interface.endpoints;
inEndpoint.startPoll();
// inEndpoint.transferType = 2;
inEndpoint.on('data', (d) => {
console.log("usb data:", d, " len:", d.length)
});
inEndpoint.on('error', function (error) {
console.log("on error", error);
});
我做错什么了吗？
在您发现一些登录信息的情况下，我认为我做的所有事情都正确，但是它必须对节点做一些事情。
