【摘要】 本文通过对Windows环境下3G-USB上网卡设备初始化过程的研究分析,提出了一种通用的USB移动上网设备在Linux平台下的用户态驱动方法,并用多种3G-USB上网卡在龙芯上网本Yeeloong 8089上进行实验验证,实验结果表明该方法有效且性能优良,理论上该方法可以解决此类设备对多种标准(包括TD-SCDMA、WCDMA、CDMA2000、GPRS、CDMA等)及其多个品牌的模块在Linux平台上的兼容性问题。更多还原

【Abstract】 Through the research and analysis on the 3G-USB module initialization process in Windows environment, this paper proposes a generic user space driver design method in Linux-based Netbook platforms for USB Mobile Network Device.We have done experiments to test the method with kinds of 3G-USB cards on Loongson Notebook Yeeloong 8089, the results show that this method is effective and good performance. In theory, our method can resolve the compatibility issues in Linux-based platform for such kind facility’s modules with different standars such as TD-SCDMA, WCDMA, CDMA2000, GPRS, CDMA and so on and brands.更多还原
