Device Descriptor Read/64 Error 71: Causes and Fixes
The “device descriptor read/64, error -71” is a common USB error that signals a communication breakdown between a USB device and the host computer. This error usually happens when the host attempts to read the device’s descriptor during enumeration but fails. You’ll typically find this error message in system logs like this:
In the message, [bus] and [device] represent the specific USB bus and device number involved.
Impacts of the Error
- Device Non-Recognition: The operating system does not recognize the USB device.
- Loss of Functionality: USB devices like keyboards, mice, or storage devices won’t work.
- System Instability: Frequent errors can lead to system crashes, especially during startup or operation.
Common Causes and Fixes
1. Faulty USB Cable or Port
Cause: Damaged or poor-quality cables and malfunctioning ports can disrupt USB communication.
Fix:
Check the USB cable for any visible damage such as frays or bends.
Try a new, high-quality cable.
Test the device with different USB ports to see if the issue is with a specific port.
2. Power Supply Issues
Cause: Not enough power can cause enumeration failures, especially with high-power devices.
Fix:
Make sure the computer’s power supply is adequate.
Use a powered USB hub for devices that need extra power.
Consider upgrading the computer’s power supply (PSU) if needed.
3. Driver Issues
Cause: Outdated or corrupted USB drivers can block communication.
Fix:
Open Device Manager (on Windows).
Expand “Universal Serial Bus controllers.”
Right-click on each USB driver and select “Update driver” > “Search automatically for updated driver software.”
If the issue persists, uninstall the drivers and restart your computer. Windows will automatically reinstall them.
4. USB Device Malfunction
Cause: A defective or incompatible USB device might cause the error.
Fix:
Test the USB device on a different computer.
If it fails elsewhere, contemplate replacing the device.
Check for compatibility with the system and update the device’s firmware if available.
5. Operating System Bugs
Cause: Bugs or updates in the OS might interfere with USB device handling.
Fix:
Check for any OS updates that might fix the bug.
If the problem appeared after a recent update, try rolling back the update.
Restart your computer after you’ve made these changes.
6. BIOS/UEFI Settings
Cause: Incorrect BIOS/UEFI settings can cause issues with how USB devices are initialized.
Fix:
Access the BIOS/UEFI settings (usually by pressing F2, DEL, or ESC while the computer starts).
Make sure USB support is enabled in the USB configuration settings.
If needed, reset the BIOS to default settings, save the changes, and exit.
7. Conflicting Devices
Cause: Too many USB devices could cause interference during enumeration.
Fix:
Disconnect all USB devices except the one causing the issue.
Restart the system and test the device.
Gradually reconnect other devices to see if any are causing conflicts.
Preventing Future Errors
To lower the chances of getting the “device descriptor read/64, error -71” error:
- Regularly Update Software: Keep your operating system, drivers, and firmware up-to-date.
- Use High-Quality Cables and Hubs: Use reliable hardware to avoid power and communication issues.
- Periodically Test Hardware: Check USB devices, ports, and cables for damage.
- Distribute Connections: Avoid overloading USB ports by using powered hubs for multiple devices.
- Maintain BIOS Firmware: Keep your BIOS/UEFI firmware updated to ensure compatibility with hardware.
