In my case, I think the problem is trying to boot from the USB-3
ports, not writing to the USB-3 port.
Just out of curiosity, have you been through your BIOS/UEFI to see if
there were boot options for those ports? (I'd solve your other issues
first, leave this for afterwards.)

I used mediawriter. I don't see how simply using dd could work.
It would depend on the image that you were copying to a drive. If the
image has a suitable bootblock for USB flash drives, and your
motherboard, then it can make bootable ones.
I see that, using mediawriter puts only one file into my Downloads
directory, but 5 top-level directories end up on my stick (was
new/empty beforehand). That suggests that mediawriter did more than
merely download and then copy.
While that's true, it's the same kind of thing with using dd. Either
way, you copy an *image* of a file system to a device. When that
devices is booted/mounted normally, it's a pre-made file system.
The specialist tools sometimes give you more options.
