急急急，在虚拟机Ubuntu上编译驱动模块，在开发板上加载驱动错误

Frog1228 2015-08-17 04:45:37
因为我需要在开发板上连接一个USB转串口的设备，而内核中没有编译进相关驱动，所以无法识别出该设备，usb转串口线的芯片是pl2303，因此需要编译加载它的驱动。
以模块方式编译，加载过程如下：
在内核所在目录，键入：
make menuconfig
打开内核配置菜单项，在usb support项中配置USB Serial Converter Surpport相关的选项。USB Serial Converter Surpport这个配置成M，usb generic serial driver选中，usb prolific 2303 single port serial driver配成M。保存退出。
然后在内核所在目录，编译：
make -C /home/tl/omapl138/linux-3.3 M=drivers/usb/serial/  modules

生成：

在/home/tl/omapl138/linux-3.3/drivers/usb/serial/ 目录下将usbserial.ko和pl2303.ko拷贝到开发板任意目录下，用modprobe或者insmod加载驱动，提示：
Error: could not insert module /lib/modules/usbserial.ko: Invalid module format
我在网上查过，大多是说编译记载版本号的字符串和当前正在运行的内核模块的不一样，他们都能从系统文件日志里（通过 cat /var/log/messages | tail 或者 dmesg | ）找到对应的提示信息，但是我的根本没有和刚才加载驱动有关的任何信息。还有一点比较奇怪的是我查看了一下pl2303.ko模块依赖，竟然是空的，应该是依赖于usbserial.ko。
本人是新新新新新新手，刚接触Linux，嵌入式系统，MakeFile我也不是很熟悉，我有几个问题想请问一下：
1. 我在Ubuntu上编译Linux3.3内核的驱动，用的应该是内核自己提供的makefile，网上找到的资料都是自己编写的驱动模块，makefile都是自己写的，而且都是直接在PC上编译，不是用作嵌入式系统上用，那是不是makefile有问题，要修改一下？
2. 如何在Ubuntu上查看Linux3.3内核的具体版本信息，用uname之类查到的都是Ubuntu的版本信息。
这是以模块的方式加载驱动，不需要重新编译内核，如果实在不行的话，我再把驱动编译进内核，但是我觉得这样太烦。
搞了几天，查了很多资料都没有解决，这里也无人可问，短期内要解决实在没办法。

再把驱动拷到开发板上加载，结果和之前是完全一样的，pl2303.ko的depends还是空的，照理说应该是usbserial.ko，我查过Ubuntu下的pl2303.ko就是依赖于usbserial.ko的，请问还有什么地方有问题的？高手，帮帮忙。
