The 3rd USB port of my machine no longer works

Hello, I found that the 3rd USB port of my machine no longer works. That is, nothing happens when I connect a USB key or an external hard drive. The port is like “extinct”. Does anyone have a solution (and an explanation) gives me please!?

If you’re dualbooting with Win does it work there? If it’s Manjaro only try booting a live USB and see if it’s working there.

Copy paste the output (no screenshots - no photos - thank you) using a code fence

System info using inxi to deduct whether this could be a simple cable connection (Desktop vs. Laptop)

inxi -M

Open a terminal and start udevadm with the monitor options

udevadm monitor

Then plug a device and check the output (plug and remove all ports).

You can also use the command lsusb to list attached devices


That depends on the output from above commands - it may be as simple as - it is broken … or disconnected … in any case - not likely the fault of the operating system unless your have an insanely peculiar system.

It does not work, even if I boot under live usb or in dual boot

What does not work?

If you are referring to the port being absent in lsusb, or that udevadm monitor does not show any activity - then your system may be defective.

You are ignoring requests, asking to provide some textual data using various commands but you provide none.

How do you expect any member to provide useful feedback?

inxi -F
udevadm monitor
inxi -F                                                                                                                     INT ✘  4s 

monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

with udevadm - you need to plug a device into the various ports of your system and record what happens when you add and remove it.

If there is no reaction at the port - then the port is not recognized by the system - the why cannot always be explained.

Your firmware indicates a 7year old laptop - it may be the port which has been worn and torn by years of usage - perhaps one or more of the soldering point where the port is connected to the mainboard is broken.

OK I understand, thank you very much

Hello, I just found the anomaly. In fact, by opening the pc this morning, I saw that the usb port in question was defective (physically). Its filaments were cut, so the problem does not come from the software.
I took the opportunity to install a new 8GB DDR3 L RAM strip, and that gives me 16GB in all. Manjaro works wonderfully!
