Possible Causes of RTL8153B-VB-CG Initialization Failure

Driver Issues Outdated or Missing Drivers : The most common cause of initialization failures is missing or outdated Drivers . Corrupt Driver Files: Even if the driver is installed, it might be corrupted, leading to initialization issues. USB Port Problems Insufficient Power : The device might not be receiving enough power from the USB port, causing initialization failure. Faulty USB Port: A defective USB port can prevent proper communication between the RTL8153B and the computer. Firmware or Hardware Incompatibility Firmware Outdated: Sometimes, the firmware on the RTL8153B can be outdated and may not be fully compatible with your system. Hardware Conflict: The device might conflict with other installed hardware, causing issues during startup. Operating System or Configuration Issues OS Compatibility: The operating system may not be fully compatible with the RTL8153B-VB-CG. Disabled Network Services: Network services or adapters might be disabled in your system settings, preventing the Ethernet controller from initializing properly.

Step-by-Step Troubleshooting and Solution

Step 1: Check USB Port and Power Supply Try a Different USB Port: If you are using a USB 2.0 port, switch to a USB 3.0 port. USB 3.0 offers more power and better data transfer speeds. Test the Device on Another Computer: Plug the RTL8153B into a different computer to rule out hardware issues with your primary machine. Step 2: Update or Reinstall the Drivers Check for the Latest Driver: Visit the Realtek website or the device manufacturer's support page for the latest drivers. Download and install the most recent version of the driver for your operating system. Reinstall the Driver: Open Device Manager (press Win + X and choose Device Manager). Locate the RTL8153B-VB-CG under "Network adapters." Right-click and choose Uninstall device. After uninstalling, unplug the device and restart your computer. Reconnect the RTL8153B and allow Windows to automatically reinstall the driver. Step 3: Update Firmware Check for Firmware Updates: Some manufacturers provide firmware updates for the RTL8153B-VB-CG. Check the product page or user manual for any available updates. If an update is available, follow the manufacturer's instructions to flash the firmware. Step 4: Adjust Power Management Settings Disable USB Power Saving: Go to Device Manager. Expand Universal Serial Bus controllers. Right-click each USB Root Hub and choose Properties. Under the Power Management tab, uncheck Allow the computer to turn off this device to save power. Click OK and restart your system. Step 5: Ensure Network Services are Enabled Check Network Settings: Open Control Panel and navigate to Network and Sharing Center. Click on Change adapter settings. Ensure that the RTL8153B-VB-CG Ethernet adapter is enabled. If it's disabled, right-click and choose Enable. Step 6: Check for Operating System Compatibility Verify OS Support: Ensure that your operating system supports the RTL8153B-VB-CG. Most modern versions of Windows, macOS, and Linux should support this device, but you may need to install specific drivers for Linux or older operating systems. If you're on a Linux system, make sure the kernel supports the RTL8153B. You may need to update your Linux kernel or install specific drivers via package managers. Step 7: Test the Adapter on Another Device Test on Another Device: To rule out hardware issues with the RTL8153B-VB-CG itself, test the adapter on a different computer. If the device works fine on another machine, the issue is likely with your computer's configuration. If it doesn't work on another machine, consider contacting the manufacturer for a replacement.

Conclusion

By following the steps above, you should be able to resolve the issue where the RTL8153B-VB-CG fails to initialize on startup. Start with the basic checks such as trying different USB ports and updating drivers, then move on to more advanced steps like checking for firmware updates and adjusting power management settings. If the issue persists, consider contacting the device's manufacturer for further assistance or to request a replacement if the device is faulty.
