USB 2.0 Specification Engineering Change Notice (ECN) #1: Mini-B connector Date: 10/20/2000 Reason for ECN: The USB 2.0 specified device-side connector – the B connector – is too large for use with a new generation of handheld and mobile devices, e.g., cell phones which would benefit from connectivity to the PC. This ECN incorporates a specification of a device-side mini connector (hereafter r
