你好，
我正在使用CY8CKIT-049原型工具包，当我突然收到Windows错误信息“USB设备未被识别：连接到这台计算机的设备之一出现故障，Windows无法识别它。”当尝试使用UB-UART桥和UART引导程序上传新程序时。加载器。之前我已经上传了大约四个程序，但是在第五次插入设备时，我收到了上面的错误信息。我尝试了不同的USB端口和检查驱动程序，但无法解决这个问题。COM端口不再出现在PSoC Creator的Bootloader主机工具中，USB串行配置工具无法识别它。
经过进一步的思考，我想我可能在我尝试上传第五次的时候，在目标（可能是UART PIN）上短了几针。
是否有一些故障排除程序？或者是USB串行桥式烤面包机，我应该买一个新的？
谢谢您。

Hello,
I was working with the CY8CKIT-049 prototyping kit when I suddenly got the Windows error message "USB Device not recognized: One of the devices attached to this computer has malfunctioned and windows does not recognize it." when trying to upload a new program using the USB-UART bridge and UART bootloader. I had been able to upload about four programs previously, but upon plugging in the device a fifth time, I received the above error message. I tried different USB ports and checking for drivers, but was unable to resolve the issue. The COM port no longer appeared in the bootloader host tool in PSoC Creator, and the USB-Serial Configuration Utility was not able to recognize it.
Upon further reflection, I think I may have shorted a couple pins on the target (which may have been the UART pins) when I was trying to upload a fifth time.
Is there some troubleshooting procedure I am missing? Or is the USB-Serial bridge toast and I should just buy a new one?
Thank You.
