Select the Start button, then select Settings Devices USB. Open USB settings. Select or clear the Notify me if there are issues connecting to USB devices box.

There might be an issue with the USB port. Try connecting to a different USB port. If the USB device displays in Device Manager after connecting the cable to a different port, then uninstall and reinstall the USB device software driver. Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC. Application software can access the USB device in the same way as it would access a standard COM port.

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.

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

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.

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).

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.

Most hardware drivers for PCI and DMA-based audio devices are based on the Port Class library, which is accessible through the PortCls system driver (Portcls.sys). PortCls is an audio port-class driver that Microsoft includes as part of the operating system. PortCls supplies a set of port drivers that implement most of the generic kernel streaming (KS) filter functionality. Therefore, PortCls simplifies the task of the audio driver developer. The hardware vendor only has to supply a set of miniport drivers to handle the hardware-specific functions of an audio adapter.

Although hardware vendors have the option to implement their own KS filters for their audio devices, this option is both difficult and unnecessary for typical audio devices. You can develop a KS filter to conform to either Stream.sys, the Stream class driver, or Avstream.sys, the AVStream class driver. But a KS filter that is based on Stream.sys cannot take advantage of the improvements that are only available in AVStream. For more information about KS filters and PortCls, see Getting Started with WDM Audio Drivers.

The internal implementation of PortCls can evolve to take advantage of kernel streaming improvements in successive Windows releases while it maintains compatibility with existing drivers.

PortCls is implemented in the Portcls.sys system file as an export driver (a kernel-mode DLL) and contains the following items:

• A set of helper functions that can be called by the adapter driver

• A collection of audio port drivers

It is the responsibility of the hardware vendor of an audio device, to provide an adapter driver. The adapter driver includes initialization and miniport driver-management code (including the DriverEntry function) and a collection of audio miniport drivers.

When the operating system loads the adapter driver, the adapter driver creates a set of miniport driver objects and prompts the PortCls system driver to create a corresponding set of port driver objects. (The code example in Subdevice Creation illustrates this process.) These port drivers are typically a subset of those that are available in the Portcls.sys file. Each miniport driver binds itself to a matching port driver from Portcls.sys to form a complete subdevice driver. The combination port-and-miniport subdevice driver is a KS filter (see Audio Filters). For example, a typical adapter driver might contain three miniport drivers: WaveRT, DMusUART, and Topology (with IMiniportWaveRT, IMiniportDMus, and IMiniportTopology interfaces). During initialization, these miniport drivers are bound to the WaveRT, DMus, and Topology port drivers (with IPortWaveRT, IPortDMus, and IPortTopology interfaces) that are contained in the Portcls.sys file. Each of these three subdevice drivers takes the form of a KS filter. The three filters together expose the complete functionality of the audio adapter.

Typically, the port drivers provide the majority of the functionality for each class of audio subdevice. For example, the WaveRT port driver does most of the work that is required to stream audio data to a DMA-based audio device, whereas the miniport driver provides device-specific details such as the DMA address and device name.

Audio adapter drivers and miniport drivers are typically written in Microsoft C++ and make extensive use of COM interfaces. The port-miniport driver architecture promotes modular design. Miniport driver writers should implement their driver as a C++ class derived from the IMiniport interface, which is defined in the header file Portcls.h. Hardware initialization takes place at driver load time--typically in the Init method of the IMiniport-derived class (for example, IMiniportWaveRT::Init). For more information about COM implementations of audio miniport drivers, see COM in the Kernel.

The following diagram illustrates the relationship between port and miniport drivers and their position in the audio stack.

In the preceding diagram, the KSEndpoint component is a system-supplied file that is provided with Windows Vista and later versions of Windows. This component is provided in the form of a DLL (Audiokse.dll). KSEndpoint abstracts the kernel-mode device endpoint, and provides the audio engine with access to the abstracted endpoint. For more information about the audio engine, see Exploring the Windows Vista Audio Engine.

The legend in the preceding diagram shows the boxes that represent driver components that the vendor provides. Note that the upper edge of each miniport driver interfaces to the lower edge of each port driver. For example, the WaveRT port driver exposes an IPortWaveRT interface to the WaveRT miniport driver, which exposes an IMiniportWaveRT interface to the port driver. These interfaces are sometimes referred to as upper-edge and lower-edge interfaces.

The port class and AVStream class drivers are similar in that they are both WDM drivers and they both support the WDM kernel streaming architecture. However, port class drivers differ from AVStream class drivers in the areas of multiprocessor handling and reentrancy. Port class drivers do the following:

Drivers Cesinel Port Devices Terminal

• Use a three-tiered approach that combines the class driver, port drivers, and vendor-supplied miniport drivers.

• Have a restricted number of audio functions, allowing miniport drivers to operate closer to the audio hardware.

• Allow several port or miniport drivers to be linked for a specific device. This feature allows for better support for multifunction cards.

• Do not support external buses (for example, USB). All port drivers support devices that reside on the system buses (PCMCIA, and PCI).

The terminology for describing WDM audio ports and miniport drivers differs in some respects from the terms that are used for other classes of Windows drivers. These differences are explained in WDM Audio Terminology.
