可能U盘损坏，或者电脑U盘插口损坏。
其实U盘的使用方法很简单，每次咱们需要使用到U盘的时候，只需要将U盘插入电脑的USB接口之后，电脑便会自动的开始识别设备，然后在咱们电脑磁盘的显示处便会出现U盘对应的盘符。
咱们就可以开始使用U盘了。但是最近，有朋友发现，u盘在别的电脑可以识别自己电脑无法识别，在电脑磁盘的地方也没有再出现U盘所在的盘符信息了。
首先，咱们需要确认不是U盘本身出现了故障，大家可以在别的电脑上先试试自己的U盘，如果别的电脑可以识别的话，那么大家便进入到下一步的操作之中。
咱们同时按下键盘上的win+R快捷键打开电脑的运行窗口，然后在窗口中输入regedit并单击回车，这样就可以打开电脑的注册表编辑器窗口了。
