So i was running my Pi 3 from USB (without sdcard) for quite some time without any issues. After updating system yesterday, it wont detect USB anymore. It same stick and Pi as before. Pi does boot from SD and even recognizes the USB if plugged in after boot. It just wont detect it during boot.
Thanks for help.

Does anything on your Raspberry get too hot to touch very quickly?
If not, try rebuilding a new USB stick with Raspbian 2017-11-29.

Here you can see USB is detected without any issues when GNU/Linux is already running (using same USB drive and port)

You're much more likely to fix your problem with "Das U-boot" by starting here:

So Pi still does load U-Boot from USB then?

A couple of users seem to be having problems after upgrading. Is it the same with your SD card, or is that still running a previous version.
(I'd just put the old version back onto your pendrive.)
Personally, I seldom upgrade, unless there is a security risk, or I want a later version of some program, but then I just update that one program.

the whole outout on your first screenshot is from U-Boot. so U-Boot is loaded and is running.
maybe the update destroyed some configuration files that U-Boot is expecting.
i guess if the updating software isn't expecting a foreign software it is possible that it overrides stuff.
why you are using U-Boot? i thought RPi3 is able to boot from USB and ethernet into raspbian, without any
foreign software.
