STEVAL-MKI109V2 USB驱动程序无法加载

我有一个
STEVAL-MKI109V2板用于评估MEMS加速度计。
我从ST网站下载了用于Windows的Unico软件（我正在运行Windows 7）并安装它。
我没有意识到USB驱动程序安装是独立的，所以当我将设备插入我的计算机时，它无法识别。
所以我拔掉了eval板，安装了1.04版（当前版本）的USB驱动程序。
安装成功，但是当我插入电路板时，驱动程序无法加载，设备管理器报告代码28，这意味着找不到驱动程序。
我尝试重新启动，卸载，重新安装，没有任何工作。我找到了ST USB设备的注册表项并尝试删除它，但Windows不允许我这样做。这已经变得非常痛苦。
在插入主板之前，我去了另一台Windows计算机并安装了驱动程序和Unico应用程序，它第一次完美运行。
所以现在我有一台与eval板一起使用的计算机和一台没有计算机的计算机，效果不是很好。
我浏览了论坛，谷歌和YouTube，但我尝试的任何东西都修复了我的Windows 7机器上的问题。
为什么即使安装了Windows，Windows也找不到驱动程序？

I have an
STEVAL-MKI109V2 board for evaluating MEMS accelerometers.

I downloaded the Unico software for Windows (I'm running Windows 7) from the ST website and installed it.

I didn't realize the USB driver install was separate, so when I plugged in the device into my computer it wasn't recognized.

So I unplugged the eval board, installed version 1.04 (current version) of the USB driver.

The install was successful, but when I plug in the board, the driver does not load, device manager reports Code 28, which means the driver was not found.

I tried rebooting, uninstalling, reinstalling, nothing worked. I found the registry entry for the ST USB device and tried to delete it, but Windows would not allow me to do that. This has become really painful.

I went to another Windows computer and installed the driver and Unico app before plugging in the board and it worked perfectly the first time.

So now I have one computer that works with the eval board and one that doesn't, not a great result.

I scoured the forums, Google, and YouTube, but nothing I tried has fixed the problem on my Windows 7 machine.

Why doesn't Windows find the driver even though it is installed?
