Windows 8 pc中的USB电缆无法识别arduino leonardo [英] arduino leonardo not recognized by usb cable in windows 8 pc

问题描述

实际上arduino leonardo可以正常工作，但是从最近2个小时开始，当我通过usb电缆将其连接到我的PC时，它表明未识别到usb，甚至在设备管理器中也没有显示.

Actually the arduino leonardo working properly but from last 2 hrs when I connect it to my pc through usb cable it is telling something like usb is not recognized and even in device manager it is not showing.

当我按下arduino中的重新启动按钮时，它将检测为arduino leonardo bootloader(com 7)，但几秒钟后消失.

When I press restart button in arduino it will detect as arduino leonardo bootloader(com 7) but after few seconds it dissappears.

我已经尝试做些什么:

• 重启电脑
• 更改了USB电缆

但同样的问题.

我通过连接其他设备检查了USB，它工作正常，但无法识别到arduino.我也在其他电脑上尝试过，但相同的问题仍在继续.

I checked usb by connecting other devices it works fine but the arduino is not recognized. I tried in other pcs also but the same problem continued.

我该怎么办?

推荐答案

重新安装/更新arduino leonardo驱动程序，并查看问题是否已解决.

Reinstall/update arduino leonardo drivers and see if the problem is solved.
