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.

Ports with connected devices show a blue and red USB icon, while ports not currently in use show a blue USB icon. Adjacent to the ports in use you'll also see a generic name on the right. Device Manager shows all the devices that are connected to your computer. To fix a dead USB port, we need to analyze Universal Series Bus controllers and associated drivers. Open Device Manager by right-clicking on Start Device Manager. From the Device Manager, scroll down to Universal Serial Bus Controllers and expand it. To communicate with MUTT devices, you need the MUTT software package. This package contains several test tools and drivers that let hardware test engineers test interoperability of their USB controller or hub with the Microsoft USB driver stack. The test tools validate USB host controller software, hardware (including firmware) and any USB hub that is installed between the host controller and the device. If for some reason, the Firewire port stops working, just go into Device Manager and make sure the IEEE 1394 device drive is still set to Legacy. The Fix for Windows 7 For Windows 7 simply replace the new 1394 driver with the Legacy driver that comes with Windows 7.

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.

Resolving the error ‘USB device might not be working properly’

If your computer does not support the device you’re trying to connect via USB-C, you will see this error message. It is also possible that the power on your laptop is limited because you’re sourcing it from your battery. In this case, you can try using a different computer, or you can try plugging your device into an external power source.

What to do when you get a ‘Use a different USB port’ prompt

When you get this error notification, it is likely that the USB port does not support Thunderbolt, DisplayPort, or MHL. If this is the case, then you can try using a different port on your PC. It is also possible that the functionality of the USB device had become limited when you connected it to a particular port. You can try plugging it to a different port on your computer to resolve the problem.

Resolving the error ‘USB or Thunderbolt device functionality might be limited’

The reasons behind this error notification are similar to what caused the limited display connection issues. So, you can resolve this by making sure that your PC and cable support the same USB-C features as the device you’re trying to connect. You also have to make sure that the dongle is directly connected to your computer.

This topic describes the tasks that you must complete before you test your USB hub by using the Windows Hardware Lab Kit (Windows HLK):

• USB Device.Connectivity Testing Prerequisites.

• USB Device.Connectivity Testing Prerequisites.

• USB Device.Connectivity Testing Prerequisites.

Hardware requirements

The following hardware is required for USB device testing. You might need additional hardware if the device includes additional features.

• One test computer. The test computer must meet Windows HLK prerequisites and include a USB 2.0-compliant controller and a USB 3.0 or xHCI-compliant controller. The controllers can be either embedded or included on an adapter that is attached or installed in the test computer. For more information, see Windows HLK Prerequisites.

• One USB device to connect to the test hub. If you are testing a USB 3.0 hub, you need a USB 3.0-compliant device. Otherwise a high or low speed USB device is sufficient.

• One USB test hub (for USB 2.0 compliant hubs) or two USB 3.0 test hubs. USB 3.0 hubs require another USB 3.0 hub to validate port mapping in the USB Hub Exposed Port Test.

  Note

  Two identical USB test hubs are required to verify the USB serial number is unique for classes of USB devices that include a USB serial number.

Note

To certify your product for use on servers, the test computer must support four processors and a minimum of 1 GB of RAM. These system capabilities are required to test the Rebalance, D3 State, and Multiple Processor Group functionality of the device and driver. You do not need a computer that actually has more than 64 processors to test your device. Additionally, the server system(s) being used for device or driver testing must have Server Core installed prior to testing. For more information see Windows Server Installation Options.

If you use a pool of test computers to test devices, at least one computer in the pool must contain four processors and a minimum of 1 GB of RAM. Additionally, that computer must contain the device and the driver that you want to test. As long as the driver is the same on all the computers in the pool, the system creates a schedule to run against all test computers.

For tests that do not include a driver to test, such as hard disk drive tests, the Windows HLK scheduler constrains the tests that validate the device's and driver's Rebalance, D3 State and Multiple Processor Groups functionality to run on the default test computer. You must manually configure this computer to have multiple processor groups. The default computer is the first test computer in the list. Test personnel must make sure that the first test computer in the list meets the minimum hardware requirements.

Note

Except for para-virtualization drivers (as defined by the WHCP Policies and Processes document), you may not use any form of virtualization when you test physical devices and their associated drivers for server certification or signature. All virtualization products do not support the underlying functionality that is required to pass the tests that relate to multiple processor groups, device power management, device PCI functionality, and other tests.

Note

Multiple Processor Groups SettingYou must set the value for the processor group size for Hardware Lab Kit testing of Windows Server 2008 R2 and later device drivers for certification. This is done by running bcdedit in an elevated command prompt window, using the /set option.

The commands for adding the group settings and restarting are as follows:

The commands for removing the group settings and rebooting are as follows:

Note

Code Integrity Setting

The Virtualization Based Security feature (VBS) of Windows Server 2016 must be enabled using Server Manager first.

Once that has occurred, the following Registry key must be created and set:

Software requirements

Before you run the USB tests in the Device.Connectivity category, you should install the latest Windows HLK filters or updates .

Test computer configuration

To configure the test computer for USB hub testing, follow these steps:

1. Install the appropriate Windows operating system on the test computer, and then configure the computer for your test network (the network that contains Windows HLK Studio and Windows HLK Controller).

2. Attach the USB hub to the test computer through an xHCI controller port (Windows 8) or an EHCI controller port (Windows 7). USB tests must be run while connected to the xHCI port with the exception of the USB Topology Compatibility test, which requires you to unplug and reattach the hub to other USB ports on the test computer.

   Note

   If the USB hub supports a USB serial number, attach an additional USB 3.0-compliant device to the test computer before you run the USB Serial Number test. For more information about this test, see USB Serial Number.

   To test USB 3.0 or 2.0 devices or hubs on a system running Windows 7, make sure that the device or hub is attached to a USB 2.0 port of an EHCI controller. xHCI controllers on systems running Windows 7 load non-Microsoft drivers. HLK tests cannot detect devices and hubs enumerated by third-party drivers.

3. Optionally, verify that the test device is visible from Device Manager on the test computer.

4. Install the Windows HLK client application on the test computer.

5. By using Windows HLK Studio, create a machine pool, and then move the test computer to that pool.

Make sure that the test computer is in the ready state before you begin your testing. If a test requires parameters to be set before it is run, a dialog box will be displayed for that test. Review the specific test topic for more information.

Drivers Testo Port Devices Replicator

Some Windows HLK tests require user intervention. When running tests for a submission, it is a best practice to run the automated tests in a block separately from manual tests. This prevents a manual test from interrupting completion of an automated test.
