How do I tell the kernel to stop trying to activate a broken USB port?

Problem

One of my USB ports (1-4) on my laptop is broken.I am not looking for a fix since it is a hardware issue, I am simply looking for a way to tell the kernel to stop trying to activate it because it is slowing down the activation of my working USB port. It also slows down reboots and shutdowns.

Context

CPU Info

$ uname -a

Here are the /sys/bus/usb/devices:

More Information

I have tried different settings with /sys/bus/usb/devices/usb1/power/wakeup and /sys/bus/usb/devices/usb1/power/control to no avail. The only effect from the previous commands were disabling my working USB ports which is undesirable.

How do I tell the kernel to stop trying to activate USB port 1-4?

Hi @GalacticRaph,

Have you tried a udev rule? To set one up, accoring to this page:

Create a new file in /lib/udev/rules.d using a text editor of your choice. For example:
sudo vi /lib/udev/rules.d/20-block-webcam.rules
Revoke authorization for the webcam to be accessed:
# Chicony Webcam
SUBSYSTEM=="usb", ATTRS{idVendor}=="04f2", ATTRS{idProduct}=="b330", ATTR{authorized}="0"
Reboot

I doubt it’ll be that exactly, but it might nudge you in the correct direction.

Hope it helps!

Edit:

Else, you could try this:

sudo sed --in-place s/on/off /sys/bus/usb/devices/usb1/1-4/power/control

I have absolutely no, zero, 0 idea if this’ll work. I just got the idea here. Use it at your own risk.

Thanks for the fast reply. I may be wrong, but I think the problem I’m having is at a lower level than the a udev solution can provide. I should have mentioned that the kernel will still try and fail to activate the USB port without a connected device. So the problem is the port itself, not a specific device. With that being said, I’ll look into udev, maybe it can help.

Thanks

You are wrong.
@Mirdarthos gave all informations. take it or leave it

Thank you. I stumbled upon that solution in the past and ran into an obstacle: I can’t find the PCI ID for my USB device (1-4).

My available devices are:

The problematic port is 1-4. On top of that, all of them are 0000:00:14.0. How would I specify the specific port?
