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

The following 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.

GND 0 VBUS VBUS GND D+ D- GND o ? ? ? 0 GND


Pin Name Description
1,5,8,13 GND Ground
2,12 0 probably not connected
3,4 VBUS +5 VDC
6 D+ Data +
7 D- Data -
9,10,11 ? unidentified
o it is fastener not a pin
