The stack looks like this:

If you continue to experience crashes after following these steps, consider checking your hardware for physical issues, such as a failing USB port or a faulty RAM stick, as hardware failures can sometimes mimic driver power state errors. 0x9f-3-usbxhci-image-pci.sys

It is a core Windows system driver. Removing it will break USB 3.0 and likely USB 2.0 fallback functionality, making your keyboard, mouse, and storage devices unusable. The stack looks like this: If you continue

To understand the fix, you must first understand the terminology. The error string is actually a composite of three distinct pieces of information: To understand the fix, you must first understand

This article dissects every component of this error. We will explore the underlying , the specific parameter 0x3 , and the crucial role of the usbxhci.sys driver in relation to PCI devices. By the end, you will not only understand why this error occurs but also possess a definitive toolkit for diagnosing and resolving it permanently.

Fast Startup is a frequent cause of power state failures.

The definitive hardware test: Run Ubuntu for several hours, forcing suspend/resume cycles. If Linux also crashes or shows USB errors ( dmesg | grep xhci ), replace the motherboard or disable the onboard USB controller and use an add-in PCIe USB card.
