1. An intelligent wireless local area network USB port interface device, comprising:
- a local oscillator that generates an RF local oscillation signal corresponding to an RF channel;
a receiver section operably coupled to the local oscillator to receive the RF local oscillation signal, wherein the receiver section receives an incoming RF signal, and wherein the receiver section down-converts the incoming RF signal based upon the RF local oscillation signal to produce an incoming baseband signal;
a transmitter section operably coupled to the local oscillator to receive the RF local oscillation signal, wherein the transmitter section receives an outgoing baseband signal, and wherein the transmitter section up-converts the outgoing baseband signal to produce an outgoing RF signal;
a dual host USB interface module further including a plurality of USB ports for receiving and transmitting USB format signals over a corresponding plurality of USB lines;
memory for storing wireless interface device software instructions that define logic for communicating over the plurality of USB lines;
a processing module coupled to the dual host USB interface module operable to communicate over the plurality of USB lines, the processing module further coupled to receive the wireless interface device software instructions that define logic for communicating over the plurality of USB lines from the memory; and
a baseband processor operably coupled to communicate with the processing module and to the transmitter and receiver sections wherein the processing module receives at least one of USB communications from the dual host USB interface module and wireless communications from the receiver section and determines whether to transmit the received communications over at least one of the transmitter section and the dual host USB interface module.

Abstract
An intelligent dual host USB interface module further including a plurality of USB ports for receiving and transmitting USB communication signals over a corresponding plurality of USB lines. The module is operable to receive USB communications from the intelligent dual host USB interface module and to determine whether to transmit the received communications over the intelligent dual host USB interface module to a downstream USB device or whether to process the received USB communications. The term “processing” relates to the specific type of device and respective functionality. For example, the module may be formed within a camera, a printer, an audio/video playback device such as an MP3 player, a CD player or a DVD player, a hard disk drive or a wireless access point or host. In the case of the wireless access point, “processing” relates to converting the received USB signals to outgoing RF signals and transmitting the signals to another wireless device.
