Davis Vantage Vue Problem - Solved - Reset SMC

]I have been reviewing discussions here regarding loss of communication between Weather Display and Davis devices. I have the same problem. After 15 to 30 minutes, my program, Weather Display 10.37 Mac 286 stops receiving data from the Vantage Vue. If I do anything on the screen, move the mouse, press Shift, etc., after a few minutes it starts receiving again. I have downloaded and installed the WeatherDisplaynew.dmg, the latest SiLabs drivers, but no change.

I get the following message in the Program Error Log:

ERROR: Inappropriate ioctl for device at time/date 19:19 10/04/17
ERROR: Input/output error at time/date 19:19 10/04/17

Is there anything else I should try?

Sound like your mac is powering down the USB port to save power when it detects no mouse/kb activity. Windows has a whole bunch of settings related to that, I imagine the mac has the same.

yes, that sounds like what is happening

I reset the SMC and it seems to be working now. I will observe for a day or two and report.

It’s been communicating fine since I reset the SMC (System Management Controller). I’m going to mark this thread as SOLVED.
