Prob with USB

liderbug · Published in 2016-6-17 21:00:59

I have a AcuRite 02064 5in1 weather station and a C program to read data via the USB connection. The code compiles and runs fine - then at random flatlines (no data change) for 30 min to 4 hrs then starts running fine - . If I restart the program it works correctly. If I move the WS to my desktop and run the same code it runs for days - well forever,

Suggestions? Has anyone seen this type of problem?
Tks

We have expirienced somewhat similar problems with early images (except data aquisition was done by ethernet) and have discovered that in early distros cpu governer throttling was causing cpu overheat under relatively high loads. After that cpu cores began to shutdown one after another (if cpu didn't get cooler). It caused processes served by that core to terminate with sigkill.
In newer distros throttling is fixed, so the problem vanished, but still we are now using heatsinks for our boards.
