We’re pleased to share that Chuangxin Tech has released an updated driver package for their USB‑to‑CAN interface devices (e.g., USB‑CAN, USBCAN‑I, USBCAN‑II, CANalyst‑II, etc.). Some older revisions of Chuangxin Tech hardware controllers

During device development, USBCAN drivers facilitate communication protocol implementation and debugging. The ability to parse DBC protocol data and support multiple higher-layer protocols makes these tools invaluable for software engineers working with CAN-based systems.

If you want, I can: 1) summarize installation steps for a specific OS, 2) list typical CAN baud rates and bit timing settings, or 3) help draft a short test plan to validate the adapter and driver. Which would you prefer?

For users running Ubuntu 22.04 or similar distributions, the process does not rely on traditional USB kernel drivers in the same way as other adapters. Instead, the USB driver is provided in the official Linux SDK. This abstraction layer simplifies development but requires linking against the vendor-provided shared object files.

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

If you have an old version of the driver installed, it is recommended to uninstall it first. 2. Run the Installer

Counterfeit Chuangxin Tech clones exist. The new driver includes an authentication check. If your device is a fake, the driver will show "Unknown Device - Refusing to load."
