CY7C68013A-128AXC Not Detecting USB Devices? Here's Why and How to Fix It
The CY7C68013A-128AXC is a USB 2.0 high-speed controller, commonly used in embedded systems. If you are encountering a situation where USB devices are not being detected by this controller, there could be several underlying causes. In this article, we will explore the possible reasons for this issue and provide clear, step-by-step instructions to help you troubleshoot and resolve the problem.
Common Causes of the Issue:
Power Supply Problems USB devices require sufficient power to function properly. If the power supply to the CY7C68013A-128AXC is inadequate or fluctuating, it can cause the USB devices to fail to detect.
Faulty USB Cable or Port Sometimes, the issue lies with the physical USB connection itself. A damaged USB cable or a faulty USB port could prevent proper communication between the devices and the controller.
Driver Issues The lack of proper or updated Drivers for the CY7C68013A-128AXC can cause detection problems. If your operating system doesn't have the correct Drivers , or if they are corrupted, USB devices will not be recognized.
Firmware Problems Firmware is crucial for proper controller function. An outdated or corrupted firmware version on the CY7C68013A-128AXC may cause compatibility or detection issues with USB devices.
Incorrect Configuration or Settings Incorrect settings in the system BIOS or in the configuration of the USB controller may also cause the USB devices to not be detected. This includes issues with USB mode or speed settings.
Step-by-Step Troubleshooting and Fixes
Step 1: Check Power Supply Action: Ensure that the CY7C68013A-128AXC is receiving a stable and sufficient power supply. For USB Controllers , it is typically 5V. How to Fix: If you're using a USB hub, make sure it's powered. If the system is running on battery power, try connecting to a stable power source. Step 2: Inspect the USB Cable and Ports Action: Check the USB cable connecting your device to the controller and inspect the USB port for physical damage. How to Fix: Try using a different USB cable to rule out a faulty cable. Test different USB ports on the system. If you're using an external USB hub, try connecting the device directly to the computer's USB port. Step 3: Reinstall or Update Drivers Action: The drivers are key to the communication between the USB controller and the operating system. How to Fix: Open Device Manager (press Win + X and select it). Locate your CY7C68013A-128AXC under Universal Serial Bus Controllers . Right-click and select Uninstall Device. After uninstalling, restart the computer, and the drivers should automatically reinstall. If not, you can manually download the latest drivers from the Cypress website or the product page and install them. Step 4: Update the Firmware Action: Firmware is an important factor that can affect USB device detection. How to Fix: Download the latest firmware version for your CY7C68013A-128AXC from the Cypress website. Follow the manufacturer’s instructions to flash the firmware onto the device. After updating, restart the system and check if the issue is resolved. Step 5: Check USB Controller Configuration Action: Incorrect USB settings could be the root cause of the problem. How to Fix: Reboot your system and enter the BIOS/UEFI settings (usually by pressing DEL or F2 during startup). Look for USB Configuration settings and ensure that USB 2.0 or USB 3.0 is enabled. Also, check if the USB Legacy Support is enabled. Save changes and exit BIOS. Step 6: Test with Different USB Devices Action: Sometimes, the issue is specific to the USB device being used. How to Fix: Try connecting a different USB device (such as a USB flash drive, keyboard, or mouse) to see if the problem persists. If other devices work, the issue might be with the specific USB device that’s not being detected. Step 7: Try the Controller on Another System Action: If the problem is with the controller itself, testing it on a different system can help identify whether the issue is specific to your current setup. How to Fix: Connect the CY7C68013A-128AXC to another computer and check if it detects the USB devices. If it works on a different system, the issue is likely with your current computer’s configuration.Conclusion
By following these steps, you can systematically narrow down the cause of the issue with your CY7C68013A-128AXC USB controller not detecting devices. Start with the basics—power supply, cables, and ports—before moving on to driver and firmware issues. By performing these troubleshooting steps, you should be able to resolve the problem effectively. If all else fails, contacting Cypress Support for further assistance might be necessary.
