When you plug something in, the kernel log should show something. If it doesn't then the kernel doesn't know about it, nothing in the userspace can help.
How can that be?
Make sure you're running those commands before you plug the usb in.

Also I used to have faulty usb cables, but even then the kernel showed something. Usually repeating messages because the usb cable kept dropping out and coming back in. What happens if you plug those devices directly?
The kernel does not notice the expresscard itself when I plug it in. My usb hard disk works perfectly under the other ports.
Ah, and fun fact: When plugging in the expresscard, I can reproducibly scramble my sound output for a second (the music repeats for a second after I plug it in). Still, the kernel says nothing. And no device nodes appear.

I already tried to add Can you be a little more specific about "does not work"? Nothing happens. Like, really nothing. No new hub is shown in lsusb (as it was under Ubuntu). Devices I plug in are not shown. Nothing. When you plug it in, what messages are you seeing while running these 2 commands in separate terminals: journalctl -k -f and udevadm monitor Nothing. No output.
