How to build your own UltraPort device

2008-03-22T23:36:03Z

Jjk: The cable color of the USB Type A Connector for D- and D+ was switched. Costs me a bluetooth dongle :-(

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 undermined 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.
