Disable bad USB port using udev?

Hello everyone,

I had a bad usb port which is severely delaying my boot process by timing out when trying to enumerate it. Googling says udev rules can disable it, but most of the rules I am seeing is after the hardware has been identified and assigned attributes like manufacturer name, driver and such. I cannot disable the individual port via UEFI/BIOS and it is part of a 4-device hub making the case I/O ports.

Journalctl:

kernel: usb usb5-port5: unable to enumerate USB device
kernel: usb 5-5: device not accepting address 4, error -62
kernel: usb 5-5: device descriptor read/64, error -110

My failed attempt at a udev rule:

cat /etc/udev/rules.d/55-bad-usb.rules
SUBSYSTEM=="", DEVPATH=="/devices/pci0000:00/0000:00:01.2/0000:02:00.0/0000:03:08.0/0000:09:00.3/usb5/5-0:1.0/usb5-port5", KERNEL=="usb5-port5", DRIVER=="", ATTR{disable}=="1", ATTR{authorized}=="0"
