Manufacturer Download Center: Access the latest drivers, including Setup(V1.40).exe for Windows 11, on the Zhuhai Chuangxin Technology official website.

Complete Data Packages: Chuangxin maintains a Data Download section with comprehensive info-packages for various models, including newer USB_CANFD analyzers (last updated early 2024/2025).

Software Version: The current stable version of the USBCANtool is V9.11, and the Secondary Development Library is V9.1.0.0. Installation Steps

Run the Installer: Locate Setup(V1.40).exe (or latest equivalent). Right-click and Run as administrator.

Plugin Installation: The package typically includes three mandatory plug-ins; install each sequentially following the on-screen prompts. chuangxin tech usbcan driver new

Hardware Connection: Connect the USBCAN device via USB. Windows should auto-detect the hardware.

Verification: Open Device Manager. The device should appear as "Chuangxin Tech USBCAN/CANalyst-II" under Universal Serial Bus controllers or Other devices. Technical Features

Compatibility: Supports CAN2.0A/B protocols, standard and extended frames, and baud rates from 10Kbps up to 1Mbps.

Development Support: Provides a DLL dynamic connection library and examples in VC/VB for custom application building.

Open Source Alternatives: For Python users, an unofficial userspace driver (based on pyusb) exists for cross-platform support on Windows, macOS, and Linux. If you'd like, let me know: Your Windows version (e.g., Windows 11 Pro) The latest drivers and software for Chuangxin Tech

Phase 4: Testing with the Included Utility

The new driver installs a testing app: C:\Program Files (x86)\Chuangxin Tech\USBCAN Tools\UsbcanDiag.exe

• Open it, select Device Index 0.
• Set baud rate to 500k (or match your CAN bus).
• Click Start CAN.
• Short pin 2 (CAN_L) and pin 7 (CAN_H) of the DB9 connector with a 120-ohm resistor. Send a test frame – you should see TX success and then an immediate RX echo (loopback).

Check device

dmesg | grep usbcan

Now the device appears as a standard SocketCAN interface (can0), compatible with candump, cansend, and cantools.

Known Limitations of the New Driver

• Not open source – The core DLL and kernel module are binary-only.
• No official ROS2 Humble+ package – Community support only.
• No CAN FD support – This device is classic CAN only (up to 1 Mbps).
• Chinese documentation – English manual is still a translation-in-progress.

5. Attach your device – it should appear as can0

ip link set can0 up type can bitrate 500000 candump can0

Troubleshooting Linux: If you see no such device, run lsusb and verify the vendor ID is 1d50 with product ID 606f (new driver version) vs 606e (old). The new driver requires the 606f firmware.

Step-by-Step Installation Guide for Windows 11/10

Here is the correct workflow for installing the new driver – do not plug in the device before installation.

Key Improvements

• Improved stability and reliability: Reduced packet loss and fewer disconnects during high-throughput transfers, making long-duration logging more dependable.
• Expanded OS support: Native drivers for recent Windows versions and updated compatibility for mainstream Linux kernels, lowering friction when integrating into development machines or CI systems.
• Higher throughput and lower latency: Optimization of USB data paths and buffering reduces round-trip times—important for time-sensitive applications like real-time control or CAN FD traffic.
• CAN FD and extended frame enhancements: Better handling of CAN FD frames and extended identifiers for modern vehicle networks and advanced sensor buses.
• User-space tools and sample code: Bundled utilities for basic send/receive testing plus example code in C/C++ and Python to accelerate prototyping.
• Simplified installation & automatic device recognition: Plug-and-play behavior for many systems, with installer packages and clear setup instructions.

Post-Installation:

• The driver creates a character device /dev/usbcan0 (or /dev/usbcan1 for dual-channel).
• Add your user to the dialout group: sudo usermod -a -G dialout $USER
• Test with cansend from can-utils:

  sudo modprobe ch_usbcan
  ip link set usbcan0 up type can bitrate 500000
  candump usbcan0
  

New feature: The driver now supports ethtool-style stats: Open it, select Device Index 0

cat /proc/ch_usbcan/stats

Displays dropped frames, bus errors, and IRQ counts.
