Hello,
This is mostly directed at Mark Rivers but might be of some use
to someone in the same situation as me.

I tried to use the synApps mca module R7-9 to control some Amptek
PX5 SDD readout electronics over USB (Amptek docs say the ethernet
is 10-baseT... haven't had time to test transfer rates to see if this is
still true).  I couldn't get the driver to connect, then traced the
problem to the function "drvAmptek::connectDevice()" failing on
a "hostToIPAddr()" call that fails because a valid IP address was not
given (actually is left blank for USB devices).  I got around it by
checking if "addressInfo_" is empty, and that got the app working
so that I could to some test data acquisition.  But it now occurs to
me that the entire chunk of code prior to checking "directMode_"
should be in the "if( interfaceType == DppInterfaceEthernet)" block. 
I haven't tested this yet, but it seems more appropriate.
