Ok, that worked.
I never suspected the wall powered USB hub not to be able to deliver the needed power to the Omega. Probably a cheap hug from unknown brand...( i used the same cable, so it is not it).
Also, I never suspected the battery controller not to be able to merge the power from the battery and the USB. Not very useful. Also, more than likely, when there is power outage the switch will most certainly cause a hiccup and a reboot of the CPU. This raises a couple of questions:
- regardless of the dock and it power circuitry, is there any form a reliable brown out detector and "corrector"?
- what about watchdog, there was a question on this list but nobody answered?
- how can you expect this to work years of unattended operation?
