The output scrolled rapidly.
The device should now appear under Universal Serial Bus devices as “ITEK USB-CAN Interface” or under Ports (COM & LPT) as a virtual COM port (e.g., COM5).
| Error / Symptom | Likely Cause | Solution | |----------------|--------------|----------| | | ITEK driver lacks Microsoft WHQL signature. | Reboot into Disable Driver Signature Enforcement (Shift + Restart → Troubleshoot → Advanced → Startup Settings). Or install via pnputil with admin override. | | Device shows “Code 10” – Cannot start | Conflicting driver (e.g., Windows assigned an FTDI serial driver). | In Device Manager, right-click → Uninstall device → Check “Delete driver software” → Reinstall ITEK driver. | | CAN bus remains in “Bus-Off” state | Baud rate mismatch; other nodes are transmitting, but your adapter is not syncing. | Confirm bus baud rate with an oscilloscope. Try listen-only mode first. Ensure termination resistors (only two per bus). | | No frames received (but can transmit) | Listen-only mode enabled. | Disable listen-only in config utility. | | High latency / dropped frames | USB polling interval too slow or CPU overloaded. | Reduce CAN baud rate for testing. Use a dedicated USB controller port (not a hub). Increase USB buffer size in driver settings (if configurable). | | Linux module fails to compile | Kernel headers missing or API changes. | Run sudo apt install linux-headers-$(uname -r) . Check git repo for kernel version compatibility. | itek usb can driver
Look for USB bulk transfer errors. On Windows, use or BusDog .
在 Linux 操作系统下，iTEK USBCAN 系列接口卡通常通过 子系统进行原生支持。SocketCAN 是 Linux 内核中一套开源的 CAN 驱动及网络协议栈。用户可以通过官方提供的 Linux 开发包快速部署驱动程序到指定目录（如 lib/modules/*/kernel/drivers/usb ），即可完成驱动加载。之后利用 candump 、 cansend 、 cangen 等命令行工具，开发人员即可在 Linux 环境下轻松实现 CAN 报文的捕获、生成和回放。 The output scrolled rapidly
| Symptom | Likely Cause | Fix | |---------|--------------|-----| | “Device descriptor request failed” | Corrupted EEPROM or power surge | Unplug, reboot PC, reinstall driver. | | Driver installs but no CAN traffic | Wrong bit-rate setting | Use ip link set can0 type can bitrate 500000 (Linux) or match baud rate in Windows app. | | Yellow exclamation in Device Manager (Code 10) | Driver signature enforcement (Windows 10/11) | Disable driver signature enforcement temporarily: Shift + Restart → Troubleshoot → Startup Settings → Disable driver signature enforcement. | | Linux: “Cannot find device can0” | slcan not attached | Run dmesg | grep tty to see the correct USB-to-serial port. |
: MAC users generally need to run a Windows virtual machine to use these drivers, as native macOS support is limited for these specific industrial models. CANUSB.com Related Software Tools | Reboot into Disable Driver Signature Enforcement (Shift
For developers and engineers working in Linux environments (Ubuntu, Raspberry Pi OS, etc.), Itek adapters utilizing standard SLCAN firmware do not require proprietary drivers. They integrate directly into the Linux kernel via SocketCAN.
The is far more than just a simple utility; it's the critical link that transforms your standard PC into a powerful diagnostic and development tool for the CAN bus universe. By properly downloading, installing, and configuring this driver, you unlock access to the rich feature set of iTEK hardware, including their feature-packed test software and comprehensive SDKs for custom application development. Whether you are an automotive engineer, an industrial automation specialist, or an embedded systems developer, mastering the itek usb can driver is a vital skill. By following the steps and insights in this guide, you will ensure a stable, high-performance connection to your CAN networks, enabling you to build, debug, and innovate with confidence.
After changing baud rate, you must restart the device (unplug/replug or disable/enable in Device Manager).
Re-download the latest driver package. Ensure Windows updates are caught up, or use the Driver Signature Enforcement workaround outlined in Section 3.
