以正常的流程处理
此处为了保护笔记本
我们以先软后硬的原则进行
在这之前我们使用替换方法
使用一个已知的好的鼠标
看在同一个或者说是同一批的端口上
是否正常
然后
开始正式的软原则检查
首现检测病毒木马
之后再进行测试看问题解决否
其次更换驱动
之后进行测试看问题解决否
最后一步解决方法
先使用外面的一键安装光盘
因为 在菜单选择的项目的地方
dos系统加载了鼠标的驱动
所以
完全可以在非Windows系统进行检测
鼠标
如果这样还不能解决那么我们只能说这是疑似硬件的问题了
此处对于鼠标的硬件检测因为比较专业话
建议去笔记本的维修点去进行检测
切不可自行拆装检测
但是这里我可以给你讲讲大概
因为笨笨上的u口大部分都是仰仗我们的南桥芯片的
所以我们的专业检测
全部围绕南桥芯片的进行
首现对于u口的线路进行检测
一般的u口有四条线路分别是 vcc data1 data2 gnd

电压为 5 - - -
这里有个窍门:如果data1和data2的阻值相差50欧姆那么说明南桥芯片的模块很有可能损坏

再有很多的南桥因为晶振不起振或者晶振电路有问题而出现不同的故障
大概就是如此
有什么你hi我我们一起面对

建议楼主下一个驱动精灵、或驱动人生检测一下硬件驱动呢,如果驱动没问题就用该是硬件接口的问题了

升级一下USB2.0驱动
