Hi Dirk,
My test application now works after the new file you provided was installed.  Thanks a million, I am happy now.  I will now add all the @init calls to my full size application and hopefully all will work just as well.  Thanks again,
Zen

Hello Zenon,

please try the attached version of AsynDriverInterface.cc with StreamDevice version 2.3.

I changed the location of the asynCommon->connect call. For me, that helped.
