Do you see a yellow mark in Device Manager? This is a common problem, and in this guide, we'll help you troubleshoot and resolve the issue on Windows 10.

On Windows 10, sometimes, Device Manager will show a device with a yellow exclamation mark. When this happens, it indicates that the system has encountered a problem with that particular piece of hardware.

EPHONE CE100 CDMA 1X EV-DO Rev A Diagnostics Port is developed by EPHONE Incorporated and is used by 243 users on Drivers Informer. The most later version of this driver among our users is 2.0.5.9. The bring-up tasks for a USB Connector Manager driver depend on the driver that you choose for the USB Type-C ports: The Microsoft in-box UCSI (UcmUcsiCx.sys and UcmUcsiAcpiClient.sys) driver, a UcmCx client driver, or a UcmTcpciCx client driver.

Although the yellow warning sign doesn't reveal the issue, it does tell you that Device Manager has generated an error code, which you can verify to determine the reason. Usually, it comes down to a hardware conflict of some sort, or missing or not correctly installed the driver.

In this Windows 10 guide, we'll walk you through the steps to resolve the yellow exclamation mark on a component in Device Manager.

How to fix yellow exclamation mark in Device Manager

• Go to the device manager and click on the device needing the driver that you posted the ID for. Click on the driver tab. Click on Update Driver. Select the Browse my computer for driver software option, and browse to the driver folder you unzipped. Make sure the Include Subfolders box is checked and the driver should install. Then restart the PC.
• Having an issue with your display, audio, or touchpad? Whether you're working on an Alienware, Inspiron, Latitude, or other Dell product, driver updates keep your device running at top performance. Step 1: Identify your product above. Step 2: Run the detect drivers scan to see available updates. Step 3: Choose which driver updates to install.

If you're dealing with a yellow warning sign on a piece of hardware connected to your computer, you first need to determine the reason for the error and then troubleshoot the problem.

To determine the cause of the yellow exclamation mark, use these steps:

1. Open Start.
2. Search for Device Manager and click the top result to open the console.

Once you complete the steps, you'll have an understanding of the problem with the hardware.

Uninstall device driver

If the problem is related to a driver not working correctly, before installing an updated version, you can remove it and let Windows 10 detect it again to see if that fixes the error.

To remove a device driver, use these steps:

5. Restart the computer.

After you complete the steps, Windows 10 will reinstall the driver automatically, solving conflicts and other errors.

If you continue to see the error in Device Manager, you want to update the driver to the latest version to resolve the issue with the instructions below.

Update driver using Settings

If the device shows a yellow mark, reads 'Unknown device,' and it's listed under the 'Other devices' list, installing the latest device driver through Windows Update may resolve the issue.

In the past, you're able to download drivers using Windows Update directly from the Device Manager, but this feature is no longer available. You now need to use the Windows Update settings from the Settings app.

To update a device driver to resolve the yellow exclamation mark on Windows 10, use these steps:

1. Open Settings.
2. Click on Update & Security.
3. Click on Windows Update.

4. Click the View optional updates option (if available).

5. Click on Driver updates.

6. Select the driver for the device with the yellow mark.

7. Click the Download and install button.

Once you complete the steps, the latest version of the driver available through Windows Update will install, and the yellow exclamation mark problem should no longer appear in Device Manager.

Update driver using Device Manager

If the optional updates link is missing, then it means that Windows Update doesn't have any updates for your hardware configuration. In this case, you'll need to download the latest drivers from your manufacturer support website and follow their instructions to complete the installation.

However, you can use these general steps if the manufacturer doesn't provide any guidance:

1. Open Start.
2. Search for Device Manager and click the top result to open the console.

3. Right-click the device with the yellow exclamation mark and select the Update driver option.

6. Select the extracted folder containing the driver update.
7. Check the Include subfolders option.
8. Click the Next button.
9. Click the Close button.

After you complete the steps, the driver will install, and the exclamation mark should disappear from the Device Manager.

If it's unclear whether you need to install the driver, either use your computer model information to find the driver in the manufacturer support website. Sometimes, companies like Dell provide a tool that can automatically scan, detect, and install the necessary drivers. If the tool isn't available and the device shows up an unknown, inside the device properties, in the 'Details' tab, you can grab the hardware id to search online and determine the driver you need.
