Hi Gary,

 

timeservice is not needed, just helpful.

 

OK.  It compiles clean without that.  For now I have left it in.

Works for me.

That should be autodetected.  Please sned the entire output of your build.

 

Attached is the output on the PI, with SConstruct unmodified, with timeservice turned on.

 

That is a kernel driver problem.   What kernel driver is in use for

your /dev/ttyUSB0?

 

I like that theory a lot.  Here is the pertinent output from dmesg.
