Linux kernel usb_寄存器_开发人员崩溃linux内核
这是一门课，但我们被难住了。我们目前正在为使用USBCore的Logitech摄像头编写USB驱动程序。发生的事情是我们加载模块，然后当我们连接USB摄像头时，内核崩溃并给我们一个内核跟踪（如下）。经过一段时间的调试，我们非常确定它会在探测函数中的usb_register_dev上崩溃，但我们无法找出原因。我们希望有人能给我们一些有用的建议，或者让我们走上正确的道路。我们不是在寻求答案，只是寻求指导 我们已经查看了所有的变量初始化器，根据我们的注释和示例，看起来还不错。下面是重要函数和调用跟踪的代码片段 内核（自定义学校，但基于3.2.34）： 初始化： 探测：Linux kernel usb_寄存器_开发人员崩溃linux内核,linux-kernel,usb,kernel,kernel-module,Linux Kernel,Usb,Kernel,Kernel Module,这是一门课，但我们被难住了。我们目前正在为使用USBCore的Logitech摄像头编写USB驱动程序。发生的事情是我们加载模块，然后当我们连接USB摄像头时，内核崩溃并给我们一个内核跟踪（如下）。经过一段时间的调试，我们非常确定它会在探测函数中的usb_register_dev上崩溃，但我们无法找出原因。我们希望有人能给我们一些有用的建议，或者让我们走上正确的道路。我们不是在寻求答案，只是寻求指导 我们已经查看了所有的变量初始化器，根据我们的注释和示例，看起来还不错。下面是重要函数和调用跟踪的
