You may find that all the devices in a family using my driver follow a similar timing curve (ie. i1 display family which includes the Huey, i1d3 family would be similar but different, the Spyder family), but the DTP-94 is X-Rite's firmware doing the reading, and is different hardware (A/D, not L2F devices).
