基于高通AMSS6XXX的USB Mass Storage与Modem设备的并存功能开发

针对高通AMSS6XXX软件系统中USBMass Storage设备与Modem设备之间相互冲突的现状,本文提出了一种二者并存的软件实现方案,利用纯软件的解决方式,通过分析设备原始架构、设计新的设备架构、更改软件处理流程3个方面,消除了无线网卡系统中Mass Storage设备与Modem设备并行工作引起的冲突,使两设备可以同时正常使用。整个方案由C语言实现,并进行了编程验证。结果表明,该方案可有效地消除上述设备冲突,保证其正常并行工作,并且实现简便、成本低。

Development of safe concurrence of USB Mass Storage and Modem device based on the qualcomm AMSS6XXX

To solve the vital problem that USB modem devices and mass storage devices collide with each other on the Qualcomm AMSS6XXX software system,a software-based solution was proposed and verified in this paper.After the analysis of the primitive device framework,the design of the new device framework and the modification of the software processing procedures,we eliminate the collision of the two kinds of devices by way of software.The experimental results show that our approach is capable of eliminating the col...
