USB (Universal Serial Bus) technology has revolutionized how we connect peripherals to our computers, providing a universal standard that simplifies interactions with devices such as keyboards, mice, storage drives, and printers. However, a common issue among Windows 10 users is the malfunctioning of USB ports accompanied by an error message stating “USB XHCI Compliant Host.” This article explores the causes, effects, and various solutions for this problem.
Understanding USB and XHCI
Before diving into troubleshooting, it’s important to understand what USB and XHCI (eXtensible Host Controller Interface) are. USB is a standard for connecting peripherals to computers, featuring a host (the computer) and multiple devices (the peripherals). XHCI is a standard that supports high-speed USB through improved management of data transmission over USB 3.0 connections. This standard allows for better bandwidth and the ability to connect multiple devices simultaneously.
Why USB Ports Stop Working in Windows 10
USB ports may stop functioning for several reasons, which can be broadly categorized into hardware issues, software conflicts, driver problems, and power management settings:
Hardware Issues
: Physical damage to the USB ports, the connected devices, or the motherboard can prevent proper function. Issues may arise from misuse, age, or electrical faults.
Software Conflicts
: Sometimes, recently installed software can conflict with existing drivers or system functions, leading to malfunctions in USB connectivity.
Driver Problems
: Like most hardware components, USB ports rely on drivers for functionality. If the drivers are outdated, corrupted, or incompatible with Windows 10, the ports may become unresponsive.
Power Management Settings
: Windows features power management options that allow the computer to turn off USB devices when not in use to save power. This occasionally leads to ports not responding when re-engaged.
Identifying the Issue
Before attempting to fix USB ports, it’s essential to identify whether the issue is related to the ports themselves, the specific peripherals, or underlying software. Here are some steps to diagnose the problem:
Test Devices
: Check the peripherals on another computer to confirm they are working properly.
Use Different Ports
: Try connecting the devices to different USB ports on your computer. If some ports work while others do not, the problem may lie with the faulty ports.
Check Device Manager
: Open the Device Manager by right-clicking the Start button and selecting it from the list. Under the “Universal Serial Bus controllers” category, look for any warnings or errors associated with USB devices.
Inspect Physical Connections
: Ensure that the USB connections are free from dust and debris. Sometimes, cleaning can resolve connectivity issues.
Troubleshooting USB XHCI Compliant Host Issues
If you have identified the issue corresponds to “USB XHCI Compliant Host,” here are steps to resolve it:
A simple reboot can often resolve unexplained hardware malfunctions. Restarting your computer refreshes the operating system and clears temporary configurations that may lead to problems.
Outdated or corrupt drivers are a common source of USB issues. Follow these steps to update drivers:
-
Via Device Manager
:- Right-click the Start button and select Device Manager.
- Expand the “Universal Serial Bus controllers” section.
- Right-click on “USB XHCI Compliant Host Controller” and select “Update driver.”
- Choose “Search automatically for updated driver software.” Follow the prompts.
-
Via Manufacturer’s Website
:- For specific drivers, visit the website of your computer or motherboard manufacturer. Download and install the latest version of the USB controller drivers.

Reinstalling the USB controllers can help reset any incorrect configurations:
Windows has a feature known as USB Selective Suspend, which allows the system to put USB devices to sleep. Disabling it can often resolve connectivity issues:
Sometimes, Windows may turn off USB ports to conserve power, leading to issues. To prevent this:
Microsoft regularly releases updates that can include patches and fixes for bugs affecting USB functionality.
Windows offers built-in troubleshooters that can identify and fix common problems:
Sometimes USB ports can be affected by settings in the BIOS/UEFI. Access the BIOS setup during your computer’s startup (usually by pressing Delete, F2, or F10) and look for USB configuration options. Ensure USB settings are enabled.
If USB ports were working previously and failed after a recent change (like an update or installation), performing a system restore to a previous state can be beneficial:
Advanced Solutions
If you have tried all the above methods and the USB ports still do not work, consider these advanced solutions:
Malware can disrupt the proper functioning of hardware. Running a full system scan with Windows Defender or your preferred antivirus software can help identify and eliminate potential threats.
You can attempt to reset the USB ports by using the Command Prompt:
Open Command Prompt as an administrator (type
cmd
in the search, right-click, and select “Run as administrator”).
Type the following commands, pressing Enter after each line:
In Device Manager, click on “View” and select “Show hidden devices.” Expand the “Universal Serial Bus controllers.”
Right-click on any greyed-out USB devices and select “Uninstall device.”
As a last resort, if none of the above solutions work, you might consider reinstalling Windows 10. This can rectify deep-seated issues within the operating system:
Conclusion
The “USB XHCI Compliant Host” issue is a common but frustrating problem that can prevent the effective use of USB ports in Windows 10. By understanding the underlying causes and exploring the range of solutions outlined in this article, users can effectively troubleshoot and resolve this issue.
Staying proactive with device drivers, power management settings, and regular updates can help mitigate future issues with USB connectivity. If problems persist after extensive troubleshooting, consulting with a professional technician may be necessary to diagnose the problem further or consider hardware replacements.
