[SOLVED] Disable broken USB port

I've got an HTPC that suffered a power surge through a USB device. The port is now broken and I'm getting constant messages in my logs about it:

This just keeps going on an on.

I'd like to disable to the port but it doesn't seem to be listed here:

> ls /sys/bus/usb/devices/
1-0:1.0  3-0:1.0  5-0:1.0  7-0:1.0  7-4:1.0  8-0:1.0  9-1      9-2	usb1  usb3  usb5  usb7	usb9
2-0:1.0  4-0:1.0  6-0:1.0  7-4	    7-4:1.1  9-0:1.0  9-1:1.0  9-2:1.0	usb2  usb4  usb6  usb8

Is there any way to disable the port or, if not, stop those lines from logging?

Re: [SOLVED] Disable broken USB port

I guess it should be below usb8?

/sys/bus/usb/devices/usb8/*/usb8-port2/disable

Re: [SOLVED] Disable broken USB port

Perfect. That's great progress.

> cd /sys/bus/usb/devices/usb8/8-0\:1.0/usb8-port2
> echo 1 > disable

Stopped the log messages.

Is there any way to make that persist across boots?

Many.  The easiest way I can think of is to create a single shot systemd service

Re: [SOLVED] Disable broken USB port

Thanks, that'll work. I was trying a udev rule but failing dismally!

Will mark this as solved now too.

Re: [SOLVED] Disable broken USB port

I had a similar experience across 2 rear USB-2 ports. Fortunately, the BIOS settings allowed them to be disabled via checkbox, and the error messages disappeared. But not all BIOS are equal, I know. Good luck.
