USB accessory adaptor
First Claim
1. A Universal Serial Bus (USB) adaptor for interfacing a portable communications device with a USB accessory, comprising:
- a first connector for connecting to the portable communications device, the first connector including a plurality of logic line connecting elements for connecting to logic lines in the portable communications device and at least one first USB data connecting elements for enabling data to be communicated between the portable communications device and the USB adaptor;
an encoder for communicating an operating state to the portable communications device over at least one of the plurality of logic line connecting elements of the first connector; and
a second connector for connecting to the USB accessory, the second connector including a first power connecting element for one of receiving direct current (DC) power from and sending DC power to the USB accessory, and at least one second USB data connecting elements for enabling data to be communicated between the USB accessory, the USB adaptor, and the portable communications device.

Abstract
A Universal Serial Bus (USB) adaptor (16, 16′, 16″), compatible with standard USB connectors, provides a simplified interface between a portable communications device (12) and a USB accessory (14, 14″). An encoder (28) provides an operating state to the portable communications device (12), enabling the portable communications device (12) to perform as either a USB host or a USB function accessory. A function adaptor (16′) selects its DC power source and is capable of providing DC power to a function accessory (14′). The host adaptor (16) can obtain DC power from a host accessory (14), according to USB standards.
