I fear I haven't given enough information, and my example was too sketchy.

1. There will be a number of different drivers, one for each instrument, all 
of with derive from the base class.
2. The driver objects will be contained by other, higher-level ones. These 
higher level "device" modules are derived from a common base class 
themselves. That base class has a pointer to the driver base class. The 
derived class objects will populate that pointer with the particular driver 
that they need.
3. The "device" objects will call the small set of public methods using 
polymorphism. Some methods are in the base class, others specific to a 
particular device. Mostly these route op codes and data to the driver, or 
retrieve data pulled from the instrument.
4. The drivers will have class attributes that contain state information 
about the particular instrument associated with the driver. The op code 
handlers can't be static. Here my example really failed. Mentally add 
several attributes, if you would.
