HP OmniBook Ultra 14: one USB 4 port does not recognize USB-2 devices

[yuiry]

I am experiencing an issue with one of the USB-4 ports on my HP laptop. My laptop has two USB-4 ports, and while one functions normally, the other has stopped recognizing USB-2 devices.

Here are the details of the issue:

• The affected USB-4 port still charges the laptop and passes a video signal without any issues.
• However, it does not recognize USB-2 devices, whether connected directly or through a hub.
• USB-2 peripherals such as a mouse, keyboard, and other devices do not work when plugged into this port.
• The other USB-4 port functions correctly, recognizing all USB devices, including USB-2.

I have already tried basic troubleshooting steps such as checking Device Manager for driver issues, updating firmware, and testing multiple USB-2 devices, but the issue persists.
