Asix usb到网络适配器不工作(内核2.6.32.17)

Question

我有一个Edimax USB到以太网适配器，它基于著名的ASIX AX88772B芯片，我想让它与我的板一起工作，这是一个基于ARM的板，运行嵌入式Linux，内核2.6.32.17。

根据Asix文档，这个芯片应该在这个内核中工作，没有问题，但在我的情况下却不起作用。我在内核中选择了必要的组件作为模块(asix、mii、usbnet)，在编译内核之后，我拥有了mii.ko、usbnet.ko和asix.ko文件。所以我把它们复制到了正确的地方。在将适配器插入硬件之后，我可以看到lsusb已经识别出一个新的ASIX设备，它具有PID和VID。在这之后我跑了：

root@dm368-evm:~# mod探头asix usbcore:注册的新接口驱动程序asix

您可以看到，模块已加载到内存中，没有任何错误或问题(显然，mod探头正在自动管理依赖项，我不需要手动插入mii.ko和usbnet.ko )。

root@dm368-evm:~# lsmod 使用的模块大小 西克斯11444 0 usbnet 11657 1 asix mii 3392 2 asix

但是我没有看到在命令下运行的以太网接口

ifconfig -a

我也没有在dmesg中看到任何信息。我本来希望看到一条类似于"eth0已注册“的消息，或者类似于我插入适配器时在Ubuntu中看到的消息。我还在另一个ARM硬件中使用了这个适配器，它的内核为3.50，工作正常，所以我不知道为什么它不能工作。

有一次，我试图静态地将必要的驱动程序构建到内核中，但这也没有什么区别。

我真的需要使这个工作，因为董事会没有以太网连接，我希望一个用作调试接口和FTP文件传输。

2.6.28配置的sdiff (左侧)与.config (右侧)的代码片段如下：

您应该调查您的SoC是否支持CONFIG_USB_ARCH_HAS_OHCI和CONFIG_USB_OHCI_HCD

我建议您使用make menuconfig来启用
