With the UltraPort connector being nothing else than a standard USB 1.1 interface with a proprietary connector, it should in theory be possible to transform any USB 1.1 device into an UltraPort device.
This idea is underpinned by the fact that a mechanical adapter comes with every UltraPort device, that transforms the UltraPort connector into a standard USB connector.
Pin Layout comparison
The following UltraPort pin layout has been discovered through measuring the UltraPort of a ThinkPad X21. It is not very well tested, but worked well for the author of this information. The information on the USB Type A connector pin layout has been copied from Wikipedia.
