现象：

公司一台Linux设备的U口突然出现故障，原来共16路USB端口都是正常的，出问题后只有7个正常，其余均不能使用。而且每次可用与不可用的数量不变，总是7个可用、9个不可用，但是具体的口并不固定，比如这一次键盘插入的U口不可用，重启后可能这个端口就好了，键盘可用了，但其它上一次好的端口本次又不行了。

日志：

通过dmesg或者/var/log/kern.log中的log进行截取日志，发现有以下错误：

可以看到，正常的机器中是没有usb2和usb3的，只有usb1。

解决：

经过与相关人员沟通确认，是出问题的这台机器前段时间主板上的BIOS电池被拔出了，BIOS恢复为默认设置了，默认打开了XHCI，这才导致上述问题的出现。将BIOS按照生产厂家给出的BIOS标准设置进行配置（其中包括不打开XHCI），问题解决。
