@emdzej/j2534-usb

Node.js libusb bulk-endpoint transport for @emdzej/j2534-driver. Talks directly to the Tactrix OpenPort 2.0 (VID 0x0403 / PID 0xCC4D) bypassing the kernel CDC ACM driver.

Requires elevated privileges on macOS and Linux (libusb needs to detach the kernel driver to claim the interface). On Windows you may need to install a generic WinUSB driver via Zadig.

Most users should prefer @emdzej/j2534-serial unless they need raw USB control.

Install

npm install @emdzej/j2534-driver @emdzej/j2534-usb

Use

import { J2534Device } from '@emdzej/j2534-driver';
import { createUsbTransport } from '@emdzej/j2534-usb';

const transport = await createUsbTransport();   // auto-detect by VID/PID
const dev = new J2534Device(transport);
await dev.open();
// … see @emdzej/j2534-driver
