我有一个基于着名的ASIX AX88772B芯片的Edimax USB转以太网适配器，我希望能够使用我的主板，这是一个基于ARM的主板，运行嵌入式Linux，内核为2.6.32.17
根据Asix的文档，这个芯片应该可以在这个内核中运行而不会出现问题，但它在我的情况下不起作用。我在内核中选择了必要的组件作为模块（asix，mii，usbnet），编译内核后我有mii.ko，usbnet.ko和asix.ko文件。所以我把它们复制到了正确的地方。 将适配器插入硬件后，我可以看到lsusb已经识别出具有PID和VID的新ASIX USB设备。在此之后我跑了：
root @ dm368-evm：〜＃modprobe asix
usbcore：注册新的接口驱动程序asix
你可以看到模块已经加载到内存中没有任何错误或问题（显然modprobe是自动管理依赖项，我不需要手动插入mii.ko和usbnet.ko）
root @ dm368-evm：〜＃lsmod
用于的模块尺寸 asix 11444 0
usbnet 11657 1 asix
mii 3392 2 asix，usbnet
但是在命令
下运行后我没有看到以太网接口ifconfig -a
我也没有在dmesg中看到任何消息。根据我在插入适配器时在Ubuntu中看到的内容，我本来期望得到像“eth0已注册”这样的消息。我还将此适配器与另一个具有内核3.50的ARM硬件一起使用，并且它工作正常，所以我不知道为什么它不起作用。
一旦我尝试将必要的驱动程序静态地构建到内核中，但它也没有任何区别。
我真的需要这样做，因为主板没有以太网连接，我想要一个用作调试接口和FTP文件传输。

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启用
