The interface needs to support methods that read and write large
quantities of data and provide notifications. It sounds like I need to
write a user client interface. What source code do you recommend I use
as an example?

Subject: Re: User space interface to controller.
Tom --
I need to set controller values as well as read them.
You have several alternatives. It depends on how much data you need to
pass to the controller and whether you need to get notifications from it
or if a simple synchronous operation is sufficient. You could
potentially use IORegistryEntrySetCFProperties() and override
setProperties() inside your controller subclass. Another alternative is
to write your own user client.
Is there a user space interface to an
IOSCSIParallelInterfaceController
device other than STUC, or is STUC the appropriate mechanism?
No. STUC is not appropriate. STUC is a device interface for SCSI
Architecture Model devices.
If STUC is the appropriate mechanism what values should I look
for, in
the IORegistry, in order to establish a port for communication
and
asynchronous event notification?
I believe you will be better served by trying either of the two
mechanisms listed above.
