文件系统用的debian的etch。只装了base system。能进去命令行终端，在板子上插上usb键盘＆usb鼠标都能用。
插上usb键盘时开发机上的console shell输出如下：
[ 80.013973] usb 1-1: new low speed USB device using fsl-ehci and address 3 ?
[ 80.187763] usb 1-1: configuration #1 chosen from 1 choice ?

拔掉：
[ 451.743761] usb 1-1: USB disconnect, address 3 ?

插上usb鼠标时的输出：
[ 455.633980] usb 1-1: new low speed USB device using fsl-ehci and address 4 ?
[ 455.783847] usb 1-1: configuration #1 chosen from 1 choice ?

后来通过apt－get装了xorg，gnome等。重新加载内核，连接到开发板的显示器到了debian的登录界面，提示输入用户名和密码。但这时候键盘就不能用了。按键盘上的“num lock”和“caps lock”按键，右上角的提示灯都都不亮。插上光电的usb口鼠标却能用。插上usb键盘＆usb鼠标时的输出同上。

再后来我仔细观察了开发机上的输出log：

在内核加载完usb驱动之后，按键盘上的“num lock”和“caps lock”按键，右上角的提示灯都是亮着的。但是在最后一句log输出之后（就是这句Starting periodic command scheduler: crond.），右上角的两个提示灯就灭了。

我的键盘就不能用了。真是郁闷极了。
还有，为什么我插上键盘时有两个input呢？而鼠标只有一个呢？
谢谢各位了。
