Question

电脑对USB接口对鼠标,键盘,音响有反应，对打印机和U盘没有反应，换插口也不行，求解答？

Answer 1

1、硬件方面：考虑U盘损坏，打印机没开机或打印机USB线损坏。解决，换个电脑看看可行否。再就是可能usb口电压不够，如果台式机看是否机箱后面的usb口可行，还有就是如果用了外接集线器，最好拆下不用。
2、软件方面，应该是没有禁用usb即插即用服务，但不排除某些优化类软件对U盘功能的封杀，如果安装了电脑管家、金山、鲁大师等，建议查看usb口的即插即用设置，恢复默认即可。

Answer 3

U盘应该不会啊 即插即查的USB2.0 3.0都是一样的啊
打印机的话 端口设置对吗 是LP1还是串口

Answer 4

装上驱动试一下，不行的话装个系统试一试，如果还不行有可能的就是主板的问题了。

Answer 5

打印机需要安装驱动啊，亲。U盘没反应的问题很多，有一种可能是U盘接口老化插在电脑上没反应，你换一个新U盘试试。

Answer 6

应该是主板驱动问题 建议按照个驱动精灵 扫描更新下驱动 然后插上打印机再扫描次就可以安装打印机驱动
