Hi Guy, I am testing owfs on a Pi as well. I have 6 temperature sensors and 3 8 channel I/O boards and I continually read all of them, takes about 9 seconds to get around them all. All of the files in /statistics/errors are zero, indicating no errors, however the code I am running logs each time it tries to read and it is not able to, and I am seeing a considerable number of no reads. Investigations on going but it does seem that there is a much higher incidence of no reads with temperature sensors than with I/O.
I started the tests using a Sheepwalk Electronics RPI2 adapter, which is specifically designed for the Pi, and I suspected that this may be the problem and so switched to a DS9490 USB adapter, but the no reads continue. Do you know if you are experiencing no reads?
