This issue is caused when Microsoft Windows does not properly detect the chipset or videodisplay.
Corrupt or missing motherboard or chipset drivers
Download and install the latest chipset and video card drivers. If you or someone you know built your computer, it came with the motherboard CD. This CD contains the chipset drivers. Otherwise, you can find drivers for all the major chipsets on our motherboard drivers page.
Corrupt or missing video card drivers
If installing the latest chipset or motherboard drivers doesn't resolve your issue, make sure you have the latest drivers installed for your video card. For a listing of video card drivers, see our video card drivers page.
Other PCI device that Windows cannot identify
If you tried the above two steps and your Windows Device Manager still contains an Unknown PCI device, likely the device cannot be identified.
If you that the device not being identified is installed, we suggest you obtain the latest drivers for that device. A listing of drivers is on our drivers page.
If you have recently finished installing or reinstalling Windows onto the computer and are getting the unknown PCI device, we suggest you manually identify the PCI device through the registry.

The USB-A and USB-B connection types are what most users are accustomed to. However, these days, there are more things you can achieve with the new USB-C type of connection. With this option, users can charge their computer. What’s more, they can also connect their PC to other USB-C type devices, including media players, smartphones, docking stations, and display adapters, among others.
However, we are aware that a good percentage of users are having troubles with their USB-C connection. In most cases, the problems are caused by problems with the hardware or software. Don’t worry because you can easily fix USB-C issues in a Windows 10 computer. After all. You will get notifications which you can use to determine how to resolve the problem.
What is a USB-C connector?
Developed by the USB Implementers Forum, the USB-C connection type is a tool for transmitting both power and data. It is worth noting that this was designed, certified, and released as an industry-standard connector by the members of the organization. Over 700 companies are part of the USB Implementers Forum, including Apple, Microsoft, Dell, HP, Intel, and Samsung. This is also the reason why many computer manufacturers readily accepted USB-C technology.
Is it similar to a micro USB connector?
At first glance, the USB-C connector looks a lot like a micro USB connector. However, the former has a distinct oval shape. Moreover, it is a little bit thicker to accommodate its best feature—like MagSafe and Lightning, the USB-C connector does not have an up or down orientation. You simply have to line the connector correctly, and you wouldn’t have to worry about flipping it to plug it in properly. Another key thing to remember is that the cables have the same connectors on both ends. This means that you would not have a hard time figuring out which end goes where.
Comparing USB-C and USB 3.1
The USB-C connection type’s default protocol is USB 3.1. Theoretically, at 10Gbps, USB 3.1 is twice as fast as USB 3.0. However, the ports for USB 3.1 can still be found in their original, larger shape. Such ports are referred to as ‘USB 3.1 Type-A. Generally, it has become more common to see USB 3.1 ports with USB-C connectors.

How to fix slow USB charger connected
When the ‘slow USB charger connected’ notification shows up, there are various possible reasons behind it. Here are some of them:
- You’re using a charger that is not compatible with your device or computer.
- Your charger’s power is insufficient for your device or computer. It is worth noting that devices with USB-C connectors have larger power limits. So, charging should be faster with greater levels of power, as long as the device supports USB power delivery.
- You have not properly connected the charger to the port on your device or computer.
- The cable’s power capacity is not sufficient for the charger itself, the device, or the computer.
- Your USB port is dusty or dirty, preventing proper insertion of the charger.
- You’ve connected the charger to your device or computer through an external dock or hub.
You can fix this problem by using the charger and cable that came with your device. These peripherals are designed according to industry standards. So, they have the right power capacity to speed up charging. On the other hand, you can also check if your charger is properly connected to the USB-C port on your device or computer. If the port is dusty or dirty, you can use compressed air to clean it.
Note: Systems with available USB-C connectors have higher power limits, and they can support up to 5V, 3A, or 15W.
Resolving the ‘Display connection might be limited’ error notification
There are many reasons why you see this error notification. It is possible that the dongle has new features that the cable, device, or PC do not support. You should also check if you’ve connected the dongle to the correct port or through an external dock or hub. On the other hand, it is possible that the other devices with the USB-C connection are interfering with the dongle.
You should know that a USB-C connector has Alternate Modes which you can use for non-USB connectors. These modes are HDMI, DisplayPort, and MHL. So, you can resolve the ‘Display connection might be limited’ error notification by checking if your PC, cable, and external display support the aforementioned alternate modes. You can also try to check if the dongle or device is directly connected to your computer. If it is yet the problem persists, try using a different cable.
Getting rid of the ‘PC isn’t charging’ error notification
This error notification is possibly caused by the following:
- You’ve used an incompatible charger.
- You’ve used a charger with lower power limits, preventing it from properly charging your device or computer.
- You’ve incorrectly connected the charger to the port on your PC.
- The cable’s power capacity cannot accommodate the charger.
- The USB ports are dusty or dirty, preventing proper insertion of the charger.
- You’ve connected the charger through an external hub or dock.
You can fix USB-C compatibility issues by using the charger and cable that came with your device’s or computer’s packaging. You can also use compressed air to clean the ports, enabling you to insert the dongle correctly.
Resolving ‘The USB device might not work’ error
This error notification shows up when the Windows version on your PC does not support the driver for the device you’re trying to connect to the USB-C port. So, the solution to this is to install all the latest updates for your operating system. You can do this by following the instructions below:
- Click the Search icon on your taskbar.
- Type “settings” (no quotes), then hit Enter.
- Select Update & Security.
- Click Check for Updates.
- Install the available updates.
How to fix ‘These two devices can’t communicate’ error
