This is strange... I have added some debug-output during the
BUS_select() and BUS_first() before the loop. It seems like it fails
there even if the usb-handler is closed and reopened... and then
it doesn't find any 1-wire devices on the adapter... strange..
I also set the ds1420 id at startup now

Another thing... Do you get one of those lines in your logfile?
"Set DS9490 [001/008] unique id to 81BC97240048"
I guess not... I think that you never make any full directory search on
the adapter before trigger that EMP problem. If you only do reads
to a specific device on the adapter (and

I have done some testing with it, and have managed to reconnect the
adapter even if it's unplugged manually. It's perhaps not a very
nice solution, but it works at least.

Hm. owserver do
You are right... The kernel thinks the usb adapter is physically
removed and then inserted again and get a new device number.
This problem is very fatal and question is if such thing should
be handled by owfs. It could of course be added to detect a new
1-wire adapter if it disappears, but strange

Sorry for the delay. I had my business partners here, which messed up things a lot.
I've done so

I noticed there were a missing usb_release_interface() before trying
to reconnect. That was probably why it didn't work as you wanted.

In any case, it's great that Jan has a setup where he can consistently trigger

Your logs show mainly "BUS_select_low_errors" increasing.
Unfortunately there are 5 places in file ow_bus.c function BUS_select_low
where that variable is incremented. I've added some (temporary) printf's to
run the program in foreground and flip the garbalizer.

I have actually also noticed some of those problems too... I have one
of my LCD-displays in my office very close to the lamp-switch, and
sometimes owserver has hanged at the same time as I entered the room
and switched on the lamp and just walked through the room to get a
