反馈的错误说的很清楚，没有正确获得USB设备的配置（在插入USB设备后，主机控制器驱动会通过枚举过程来探测插入的设备并进行登记造册），我想
可能死USB设备的问题，以上只是个人的理解，希望能够在进一步讨论。
我能够提一个问题吗？就是我想替换mini2440中的USB设备驱动模块（为了测试），该怎么做？找了很多方法都不行

我是用的mini2440，在win7下总是蓝屏，于是在linux下用dnw_linux，加载secbulk.ko后，插上usb下载线，第一次还能下载，以后就这个情况了，想着可能是redhat5.0太老了，今天换成Ubuntu12.04又做了一次加载，还是不行，出现问题如下：

至于你说的问题，我还没学到，我只是个新手，见谅！！！
