The XHCI-HCD function in the BIOS is designed to manage USB 3.0/3.1 ports and enable dynamic USB speed switching between USB 2.0 and USB 3.0.
During the boot process, this functionality may interfere with USB recognition, causing the USB installation media to disconnect or fail to initialize correctly.
As a result, the system hangs while attempting to access the USB device.
The installation process hangs during the USB initialization phase.
USB devices (e.g., installation media) are intermittently disconnected.
Errors related to xHCI-HCD or USB device recognition are observed in the boot logs.
To resolve the issue, follow these steps:
Create the installation media on a USB 2.0 device (low-speed USB).
Plug the USB 2.0 device into a USB 2.0 port on the motherboard.
Proceed with the installation.
Restart the system and enter the BIOS/UEFI settings.
Press the appropriate key during boot (usually Del, F2, or F10).
Locate the XHCI Hand-Off or XHCI Support setting in the BIOS.
This is typically found under Advanced USB Configuration.
Disable the XHCI function.
Save the changes and reboot the system.
Begin the installation process.
If available, connect the installation media to a legacy USB 2.0 port.
Ensure the BIOS settings prioritize legacy USB support for bootable devices.
If neither solution is feasible, consider the following:
Use a Ventoy-installed NVME SSD and put it into the 2nd slot of the motherboard, and boot it from there to prepare the Ubuntu installation.
Use a different motherboard to install Ubuntu and transfer the installed drive back to the ASUS WRX80e-SAGE system after completing the initial setup.
Ensure the BIOS firmware is updated to the latest version from the ASUS support site.
Verify the integrity of the Ubuntu installation media.
Use tools like Rufus or Etcher for creating bootable USB drives.
This issue stems from USB compatibility challenges during the boot process on ASUS WRX80e-SAGE motherboards. By using a low-speed USB device, disabling the XHCI function in BIOS, or leveraging legacy USB ports, you can ensure a smooth installation of Ubuntu Server 22.04.
