Hi, I got a LinkUSB as a master for my 1-wire net, around 80m with 30 devices. The bus is scanned every minute and temperature sensors polled (most of the devices). Around 3 times a second I try to scan the alarm dir for alarms (DS2406's), and possibly handle these.
Normally this works perfectly fine, and has done so for a few years. No re-reads or CRC errors according to the counters. However, a few times during these years, the whole network has become inaccessible, and the only way to get it back into working shape has been to unplug the LinkUSB from both the 1w-network (DQ+DGND), and the USB port. Once doing this, it all comes back up immediately, and all devices work fine. If I recall correct I have also pulled the external 5V feed to the devices too, but just disconnecting the 1w-network from the LinkUSB, and disconnecting the 5V feed has NOT been enough, the USB port must be disconnected as well. Restart of owserver does not help. Anyone else with similar experiences, or ideas on what might be causing this or how to work around it? Hard to debug since I cannot really reproduce it at will..
