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
