Hi Dennis,
Is support for this device in your plans?
As PCs with parallel ports die off, this device allows continued use of the "parallel port" functions to be carried forward on a USB port.
Now that "tablets" are replacing "lap-tops", and given "lap-tops" have been replacing desktops for several years now, the writing must be "on the wall" for the parallel port hardware registers. 
I understand Logic would drive the device using a specified protocol rather than "set bits" in status registers.
