How to turn off USB ports when computer is shut down

[sebastian23]

Hey. I'm using a Acer ConceptD 5 CN517-71-74YA (NX.C52EG.002) Laptop with Ubuntu 20.04.1 LTS and a a quite old Kensington Expert Optical Trackball Mouse (K64325) and wondering if there is a way to power off USB ports when computer is shut down, as the trackball now always consuming power, even the Laptop isn't turned on. I checked BIOS but there isn't any function to change that behavior.

This is what I see If I check state with lsusb -v:

Any advice is welcome.

Nobody?

This is not an ubuntu question - no ubuntu is active when the PC's down.
But here is how you do this:
Reboot to grub. Use UEFI firmware settings. That's it. I don't know what your BIOS and UEFI firmware looks like.
If no UEFI firmware options in GRUB, press enter or the button the system tells you to press to interrupt normal startup. If you will send me your bios photos, I'll be able to figure it out.

Yeah, that's what I meant.

I thoughts it's a Ubuntu related problem as it did not happend when I switched off Windows, which is also installed on my Laptop. But now I tried it a couple of times and it doesn't matter if Windows or Ubuntu is used before I shut down the Laptop. My Trackball switched off during shut down, but after 2 or 3 seconds LED get power again and stays on.

I guess only the first picture is relevant for you.
