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? 以上来自于谷歌翻译 以下为原文 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? |

好的,我明白了。
由于某种原因,驱动程序安装程序未正确完成。 安装程序复制了驱动程序安装文件 但它没有运行实际的驱动程序安装。当我查看该目录时,有一个文件具有在Win7或Win8子目录中运行32位或64位安装程序的指令。 我双击,然后显示实际的驱动程序安装程序启动屏幕。 这就是诀窍! 当我在第二台计算机上安装时,安装程序显然是端到端工作。 以上来自于谷歌翻译 以下为原文 OK, I figured it out. For some reason, the driver installer didn't complete properly. The installer copied driver installation files in but it did not run the actual driver install. When I looked in that directory, there was a file that had instructions to run either the 32 or 64 bit installer in the Win7 or Win8 subdirectories. I double clicked on and then the actual driver installer splash screen showed up. That did the trick! When I installed on the second computer, the installer apparently worked end to end. |
