Not powered, as I don't expect DS9490R to draw much power, but you
have a point and I can try to power them if I cascade again.  There
was no hint of anything wrong in dmesg.  All DS9040R were detected and
enumerated, and didn't drop out.

As for the owserver stability issue, I suspect that it's the same as
I've experienced before - sensors disappearing and eventually owserver
dies.  I think it happens in all versions, but given a magic
combination of owfs version, number of owserver instances, sensors and
reading frequency, it will work.  This time I didn't see sensor
fallouts before owserver died, but the reason why I saw these sensor
dropouts earlier could be related my previous use of 1-wire hubs.

It was 2.7p38 that crashed.  I'm running 2.8p13 now with error_level
9.  It's run for 6 hours now, still good.
