A USB Composite Device Driver error on Windows 11 usually appears in Device Manager when a USB device (such as a keyboard, mouse, webcam, printer, headset, or USB hub) fails to install or function properly. You may see warning messages like “Unknown USB Device”, “USB Composite Device driver error”, or a yellow exclamation mark next to the device.
This issue occurs because Windows treats many modern USB devices as composite devices—meaning a single USB connection exposes multiple functions at once. When the driver fails, some or all functions stop working. The good news is that this problem is typically caused by driver corruption, power management settings, USB port issues, or Windows update conflicts, and it can be fixed with standard troubleshooting.
Fix USB Composite Device Driver Error on Windows 11
Follow the solutions below in order. In most cases, one of the early fixes will resolve the issue.
1. Disconnect and Reconnect the USB Device
Start with the simplest step to rule out temporary detection glitches.
- Unplug the affected USB device
- Restart your PC
- Plug the device back in (preferably a different USB port)
Windows will attempt to reinstall the driver automatically.
2. Try a Different USB Port or Cable
Faulty USB ports or damaged cables commonly trigger composite device errors.
- Use a different USB port (rear ports on desktops work best)
- Avoid USB hubs or docking stations
- Replace the USB cable if the device supports one
If the device works in another port, the original port may be faulty.
3. Restart the USB Controllers
Restarting USB controllers refreshes device communication.
- Press Windows + X
- Select Device Manager
- Expand Universal Serial Bus controllers
- Right-click each USB Root Hub, USB Host Controller, and USB Composite Device
- Select Disable device
- Restart your PC
Windows will automatically re-enable and reload all USB drivers after reboot.
4. Uninstall and Reinstall the USB Composite Device Driver
Corrupted drivers are a common cause of this error.
- Open Device Manager
- Expand Universal Serial Bus controllers
- Right-click USB Composite Device
- Select Uninstall device
- Check Delete the driver software for this device (if available)
- Click Uninstall
- Restart your PC
After rebooting, Windows 11 will reinstall the correct driver automatically.
5. Update USB and Chipset Drivers
Outdated chipset drivers can prevent USB composite devices from functioning correctly.
- Open Device Manager
- Right-click USB Composite Device
- Select Update driver
- Choose Search automatically for drivers
For best results:
- Visit your PC or motherboard manufacturer’s website
- Download and install the latest chipset drivers
- Restart your system
6. Disable USB Power Management
Windows may turn off USB devices to save power, causing driver errors.
- Open Device Manager
- Expand Universal Serial Bus controllers
- Right-click USB Root Hub
- Select Properties
- Go to the Power Management tab
- Uncheck Allow the computer to turn off this device to save power
- Click OK
- Repeat for all USB Root Hubs
- Restart your PC
This prevents Windows from disabling USB devices unexpectedly.
7. Turn Off USB Selective Suspend
USB Selective Suspend can interfere with composite devices.
- Press Windows + S, type Power Plan
- Select Edit power plan
- Click Change advanced power settings
- Expand USB settings
- Expand USB selective suspend setting
- Set it to Disabled
- Click Apply > OK
- Restart your PC
8. Run Windows Hardware and Device Troubleshooter
Windows can automatically detect and fix common USB issues.
- Press Windows + I to open Settings
- Go to System > Troubleshoot
- Select Other troubleshooters
- Run Hardware and Devices (if available)
Follow the on-screen instructions to apply fixes.
9. Install Pending Windows Updates
USB driver fixes are often included in cumulative updates for Windows 11.
- Open Settings
- Go to Windows Update
- Click Check for updates
- Install all available updates
- Restart your PC
10. Check the USB Device on Another PC
This helps determine whether the problem is with Windows or the device itself.
- Connect the USB device to another PC
- If the same error appears, the device may be faulty
- If it works elsewhere, the issue is specific to your system
11. Run SFC and DISM Scans
System file corruption can affect USB driver loading.
- Open Command Prompt (Admin)
- Run:
sfc /scannow - After completion, run:
DISM /Online /Cleanup-Image /RestoreHealth - Restart your PC
Wrapping Up
With that, we wrap up our complete guide on how to fix the USB Composite Device driver error on Windows 11. While this issue can prevent USB devices from working correctly, it is usually caused by driver corruption, power management settings, outdated chipset drivers, or USB port problems, not permanent hardware damage.
By reinstalling USB drivers, disabling aggressive power-saving features, updating chipset software, and checking ports and cables, you should be able to restore normal USB functionality.
