最近经常性的开机后 鼠标键盘 均没有反应

在Grub时期键盘还能动，如果进入Windows从来不曾有问题
但是进Arch的时候三次中有一次两个全部不工作
鼠标不能移动，左右键没有效果，键盘也没用，无法切换到控制台
键盘鼠标均为USB设备，有时拔插一下能好，有时候拔插N次并且换口才行，有时只能重启
但是只要识别出来了，就可以接着稳定的用上两天两夜也不要紧。

从前没有这样的问题，windows下正常也不该是硬件问题，
可能会是近期升级Xorg之类的导致的，但不知道怎么解决，
因为三次中另外两次还都是正常的。

刚才又出现了一次，拔插五六次，换了N个口终于认出来了， hal和fam都在rc.conf里。
下面是dmesg的log，有人能看出是什么原因认不出来吗？谢谢

顶一下，希望有人知道是怎么回事儿。在鼠标键盘被识别之前的N次尝试，日志显示能找到USB插入，但是认不出是什么设备。

应该是xorg-server及其驱动升级后引发的问题。gentoo下需要卸载这些驱动并重装。

好，我试试把整个Xorg卸了再装上看看。谢谢
