Because mobile phones are getting slimmer and smaller, mini USB ports that connect phones to computers also have to catch up. There is a new standard port being developed for these small devices measuring a mere 2.2 x 2.25 x 0.6 mm. Sooner or later we will be needing a dual USB port cable to fit the standard mini USB hub as well as these micro USB ports.

The technology called Low-Pin Interface (ULPI) is being developed by NXP, a Philips subsidiary.
