First I must say I cannot reproduce the problem at my desk, but several
different customers have it. They all use a board I made which connects a
DS2482-800 to i2c on the machine. The software uses the Tcl binding to connect
to OWFS directly. It works fine most of the time. The software does a
OW::get uncached/bus.0/simultaneous/single_ds2400
every second. If the command fails 3 times, it does OW::finish, then
immediately OW::init /dev/i2c-0 again, then just OW::get to check if the host
adaptor is working. But that won't help (or won't help everytime), that
OW::get fails everytime in the situation.
I know it's hard to find the actual problem from that vague description. I
continue to try catching the error at my desk.
Kind regards
