USB issues with 12.0

[Florian Schulze]

Hi!

Yesterday I attempted to upgrade my NAS from 10.3 to 12.0. Among other 
things, I use the NAS for data gathering from an Arduino Leonardo clone 
and displaying to an USB attached Kindle with USB networking.

I created a new boot environment with beadm, mounted it and upgraded via 
chroot. Then I activated it, rebooted and finished the upgrade.

After the upgrade the Kindle and Arduino aren't working anymore. I 
noticed that uarduno.ko was blocked by an old version in /boot/kernel. 
After I removed that, the correct one from /boot/modules was loaded, but 
still the serial interface /dev/ttyU0 doesn't show up.
The uether.ko module wasn't loaded in 12.0, but loading it didn't change 
anything.

With usbconfig everything looks like with 10.3 as far as I can tell. I 
didn't copy the info. On my next try I will do that.

For now I reverted back to the 10.3 boot environment and with that 
everything is fine.

I will try 11.x next (probably this weekend).

Any hints on what I can try to debug this and get it working or helping 
with fixing a possible regression?
