What is XHCI Hand-Off?

The XHCI Hand-Off is a component responsible for the functionality of the USB 3.0 port on your computer. It controls how it works and stabilizes how your USB 3.0 port responds to usage. When you have the XHCI Hand-Off enabled on your PC, your onboard USB 3.0 ports typically behave as a 3.0 port. Furthermore, the XHCI Hand-Off mode is different from its other counterpart, the EHCI, which is responsible for USB 2.0. Most users mistake them for each other. However, the XHCI mode supports a higher USB version, making it the better one.

Should I enable XHCI Hand-Off?

Enabling the Extensible Host Controller Interface (XHCI) Hand-Off mode on your PC offers a couple of benefits to its ability to use USB ports. Because it is the most recent Intel Host Controller Interface, it is more advanced than previous versions. Some notable advantages that come with the XHCI Hand-Off enabled in your BIOS settings are:

It allows you to use and enjoy the USB 3.0 functionality on your computer. It offers a faster speed for USB 3.0 transfers by enhancing the optimal bandwidth on your USB ports. XHCI Hand-Off is compatible with the standard version 3.0 and lesser versions of Interfaces like USB 2.0. It allows your PC to access drivers that improve the USB mouse and keyboard performance. Enabling XHCI Hand-Off on your PC allows your onboard USB 3.0 ports to function like regular USB 3.0 ports. If not enabled, onboard USB 3.0 ports will function like USB 2.0 ports because they lack the drivers needed.

In short, enabling XHCI Hand-Off improves your onboard USB 3.0 ports and allows them to function to their best capabilities. Hence, we recommend you enable it. SPONSORED

How do I enable or disable XHCI hand-off?

1. Enable XHCI Hand-Off

Enabling the Extensible Host Controller Interface (XHCI) option allows your USB 3.0 to support and use the Universal Serial Bus (USB) 3.0. If you encounter any issues launching your PC into BIOS, there are other steps you can follow to get it done. So, we recommend you read through our article about the methods to enter BIOS on a Windows 7, 10 & 11 PC without issues.

2. Disable XHCI Hand-Off

However, disabling the XHCI Hand-Off will stop your USB 3.0 from using the Universal Serial Bus (USB) 3.0. Hence, it depreciates its features to that of EHCI using USB 2.0. If you encounter difficulties accessing the BIOS settings, follow the solutions in this guide to solve them. Nevertheless, you can read how to fix USB ports not working on Windows 10/11 if you experience issues. Likewise, we have a detailed guide on how to fix Mac USB ports not working in a few steps.
