The Design and Implementation of USB Mass Storage and CCID Composite Device

Article Preview

Abstract:

USB disk and UKEY are common applications of USB Mass Storage and CCID protocol and used widely in our daily life, but they are always deployed on different kinds of devices such as USB disk and UKEY. A potential application that integrates the functions of these two protocols into one device is discovered by us. In this way, we can regard a single device as a mass storage and an UKEY as well. According to this discovery, a new Mass Storage and CCID composite device is developed on IS8U192A development board. After this, several tests are made with some test tools to ensure the newly developed device is able to function well and the Mass Storage and CCID protocols are accurately implemented.
