一种基于USB协议的无线网卡自启动方法

An autorun implementation of wireless network card based on USB protocol

为了解决传统无线网卡体积大、自启动过程不稳定等问题,针对高通平台的无线网卡,根据MSM6290芯片组解决方案用一个单独的应用处理器实现单一芯片上的数字和模拟功能,并通过基于USB协议的SCSI命令处理实现虚拟光驱设备和USB协议栈的重启。实现结果显示,这种基于USB协议的无线网卡自启动方法可显著改善设备自启动的效率及稳定性,能使3G无线网卡具有更好的应用性能。

The traditional wireless network card always bulky and unstable in autorun course,now the wireless network card based on Qualcomm＇s platform use the MSM6290 chipset solution integrates both digital and analog functions into a single chip,the new device use SCSI command based on USB protocol to achieve virtual CD-ROM device and？USB stack restart.It has significant improvement in the autorun efficiency and stability of the device.Those improvements to the 3G wireless network card brought better performance and broader application prospects.
