I got this on 10.3. No data yet for 12.0, most likely tomorrow morning 
again.

# usbconfig -d 1.2 show_ifdrv

Yes, linker.hints is in /boot/kernel and /boot/modules for both 10.3 and 
12.0.

The kldstat gave me a clue on why Arduino might fail. Initially I 
complied uarduno myself, because I didn't realize it's in pkg. That 
seems to be the one in /boot/kernel. It looks like the one from pkg in 
/boot/modules isn't used on 10.3. Because I have a clone, I might have 
changed the device list in uarduno when I compiled it myself. Because 
the self compiled one still is in use, it might be that an out of the 
box uarduno on 12.0 doesn't work for me. When I try next time, I will 
move the possibly self compiled uarduno in 10.3 away to check that 
theory.

This still doesn't explain why the Kindle doesn't work.

Any tips on what to look for there?

Thanks for the help so far!
