ELM-327-USB Driver by gUeRRa

ELM-327-USB Driver is a lightweight, reliable driver package that enables Windows to detect and communicate with USB-based ELM327 OBD-II adapters. It creates a stable virtual COM port so your preferred diagnostic applications can connect to your vehicle’s OBD-II system for reading live data, retrieving and clearing trouble codes, and performing basic service tasks.

Designed for simplicity and compatibility, the driver helps reduce connection drops and “device not found” errors often seen with generic USB-to-serial solutions. Once installed, it works in the background, allowing your diagnostic software to handle the features you need.

Key features:

• Quick, straightforward installation with no extra bloat
• Establishes a virtual COM port for ELM327 USB interfaces
• Broad compatibility with many ELM327 USB adapters based on common USB-to-serial chipsets
• Stable, low-latency communication with configurable COM port and baud rate settings
• Works with popular Windows diagnostic apps (third-party software not included)
• Lightweight footprint; runs only when your adapter is connected

Requirements:

• Windows PC with an available USB port
• ELM327 USB adapter
• Administrative rights for installation
• Compatible OBD-II diagnostic software

Notes:

• This package provides connectivity; available diagnostic functions depend on the software you use and your vehicle’s capabilities.
• Always use diagnostics responsibly and only when the vehicle is safely parked.
