System and method for interfacing an electronic device with a host system

摘要

The invention relates to a system and method for controlling interfacing parameters for a device when connected to a host. The method comprises: monitoring for an initial connection by the device to the host; then, while the device is establishing the connection with the host, utilizing a communication bus controller contained in a microprocessor in the device to process communications with the host at a first data transmission rate; and after detecting that the battery has been charged to a predetermined level, re-establishing the connection with the host using a second bus controller in the device that processes the communications at a second transmission rate that is higher the first data transmission rate.
