That is because the asynSetTraceMask causes a call to
asynCommon->connect.  I had suggested this earlier to Zen.  However, I
see that you used an asyn "address" of 8, while I was suggesting 0.
Zen, are you sure you tried adding the asynSetTraceMask with the
subaddress that your @init device is actually using?
