Missing database on fresh install

[kon...@gmail.com]

LIke a few others asking question about upgrading hardware, I'm working to migrate  my current hardware to Rpi and after installing the latest weewx, I'm not seeing any .sdb file in the /var/lib/weewx directory. 

This is a fresh install so I do not yet have my station connected.  I'm wondering if I need to connect my station so the install can complete the instantiation of the database?

I'm using a standard weewx.conf file.  Here is my latest syslog entry for user weewx.

Thanks in advance,

Lean toward yes.   The os is not going to have a /dev/ttyUSB0 device if nothing is hooked up to your USB.  Secondly the driver is going to try to connect to actual Davis hardware on that port when it initializes.  Give it a try.  You can't break a clean installation anyway.

Thank you Vince.  That was the trick.
