[求助] 关于CCS3.3无法和2812连接

一开始运行都是正常的，只是在跑一个USB的例程时不知道什么原因CCS无响应，强制关闭也没用，就直接拔掉了仿真器，CCS立刻就关了，重启后2812就和CCS没法连接了，然后卸载了CCS又重新装一遍，还有SEED-XDSUSB2.0的驱动也重新装了，都是用的和以前一样的安装文件，可是还是没法连接，显示错误是

可是同一块开发板和仿真器在另一台机子上可以顺利运行，是安装出错了吗还是哪里需要设置一下？

电脑重启一下                              

重启过，不行，不过刚刚解决了，卸载了仿真器驱动重新装了一次，就好了，还是谢谢你啦

我用CCS3.3也经常出这个问题。不过不是每次都这样，总得来说也不太多，就没追究过，应该是驱动和仿真器通讯异常了，CCS上就一直在等待某个条件就绪，从而卡死
