Hi @xramm57,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand your USB 2.0 port on the left side of the PC is not working while all other USB ports work normally. Let’s go through a few steps to check what could be causing this and confirm whether it’s a software or hardware issue.

Test the port with multiple devices
Try at least two known-working USB devices (mouse, keyboard, flash drive).
If none are detected, this rules out a single faulty device.

Check Device Manager for USB controller errors
Open Device Manager and expand Universal Serial Bus controllers.
Look for any warning icons or entries that disappear/reappear when you plug something into the faulty port.

Uninstall USB controllers and reboot
In Device Manager, uninstall all USB Root Hub and Host Controller entries.
Restart the PC and allow Windows to reinstall them automatically.

Check BIOS/UEFI USB settings
Restart the PC and enter BIOS/UEFI (usually F2, F10, or Del).
Confirm that USB ports or Legacy USB support are enabled.

Test the port before Windows loads
Try entering BIOS or a boot menu using a USB keyboard plugged into the affected port.
If it doesn’t work here either, the issue is not Windows-related.

Inspect the USB port physically
Look inside the port with a flashlight for bent pins, debris, or looseness.
Even slight internal damage can cause a port to stop functioning completely.

Rule out power or overcurrent issues
Shut down the PC, unplug the power, and hold the power button for 15 seconds.
Reconnect power and test the port again.

Confirm it’s not a port-specific hardware failure
If the USB port does not work in BIOS and no device is ever detected, the port itself is likely faulty.
In this case, software fixes will not restore it.

I hope this helps.
