Hi I am running some long term tests that require data logging. If I do not touch the laptop for a few days the program continues to run and log data but it just goes to zero. If I move the mouse the laptop responds but the labjack doesn't, to get it to work I have to unplug and plug the labjack back in again, once this is done the right values are read and displayed again. The laptop does not sleep or hibernate. I was looking at this "USB selective suspend setting" under "USB settings" in advanced power settings. I am not sure what this function does and whether it affects it. Has anyone had this problem and know of a fix. Thanks

Thanks for the reply, I am using Labview, I will add error handling into my code to try and work out the problem. It is not happening on all my systems so it might be related to the laptop. To fix it, it requires the device to go through a power cycle, with the software still running (C in that guide). I might look into adding a watchdog to check the connection/communication status and then reset the device in that event. It has only happened a few times and can take days for it to happen so it is hard to get an answer to the problem straight away. Thanks for your help I will look into a solution and reply with my findings.
