推荐答案

不是整个 PC 方面的专家，但我在 Windows 10 中使用 aliexpress 的外部 ST-LINK V2 发现 PC 机器可能会选择错误的驱动程序设备默认情况下，您所做的修复就是简单地更改设备的相应驱动程序.

Not an expert in the whole PC stuff but I found out in windows 10 using external ST-LINK V2 from aliexpress that the PC machine might select the wrong driver per device by default and what you do to fix that is to simply change the corresponding driver for the device.

这是你的做法:

Hit Windows key 
Type "device manager"
Locate connected ST link device Right click-> "Update driver"
browse my PC -> Let me pick from a list available
and there you want to select STLink Dongle Version:("Your most recent")

这几乎解决了我所有的问题.

And that pretty much fixed all my problems.
