1-Wire Temperature Sensors

[Techstyle]

So I have 4 Temperature sensors installed in my 1-Wire network.

2 days back 1 was accidentally unplugged.  Since then the temperature has remained constant at the temp that was being reported - even after a reload and reboot.  what is the correct process for getting this to work again?

[_if_]

you could check if the right USB port was recognized in the devicetemplate.
other than that, 1wire has always been a misterious thing - suddenly one day they get recognized and nobody knows why 
was the serial number recognized already?

the one sensor that was disconnected was still appearing in the log on reboot - this is after the device was physically disconnected and shows that it is connected properly:

it seems like it doesn't find the device.  When I installed them less than a week ago they were discovered almost immediately.

the OneWire DCE device uses the OWFS client API. If you can see the devices in OWFS, they will appear in LinuxMCE.
