关于code composer studio 与开发板无法连接的问题解决方式（-151，错误代码0xffffff69 ）

开发板

前几天遇到如下的一个问题，开发板和软件怎么也连接不上。打开软件测试连接情况就出现下面的代码。
[Start: Texas Instruments XDS100v2 USB Emulator_0]

Execute the command:

%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -F inform,logfile=yes -S pathlength -S integrity

[Result]

-----[Print the board config pathname(s)]------------------------------------

CCSti4BrdDattestBoard.dat

-----[Print the reset-command software log-file]-----------------------------

This utility has selected a 100- or 510-class product.
This utility will load the adapter 'jioserdesu***.dll'.

An error occurred while soft opening the controller.

-----[An error has occurred and this utility has aborted]--------------------

This error is generated by TI's USCIF driver or utilities.

The value is '-151' (0xffffff69).
The title is 'SC_ERR_FTDI_OPEN'.

The explanation is:
One of the FTDI driver functions used during the connect
returned bad status or an error. The cause may be one or
more of: no XDS100 is plugged in, invalid XDS100 serial number,
blank XDS100 EEPROM, missing FTDI drivers, faulty USB cable.
Use the xds100serial command-line utility in the 'common/uscif'
folder to verify the XDS100 can be located.

根据解释说明，造成的原因有XDS100未插入，无效的XDS100序列号，空的XDS100 EEPROM，缺少FTDI驱动，USB线损坏。这么多原因我看的也是醉了。通过排查发现，开发板一切正常，排除“无效的XDS100序列号，空的XDS100 EEPROM”;重新插拔并更换USB线，排除"XDS100未插入,USB线损坏"这两种原因.好吧，剩下的就是缺少FTDI驱动了。在设备管理器中发现驱动旁边有一个感叹号。感觉应该就是驱动安装不成功。
索性我干脆就把软件卸载了重新安装了一次，然而事实还是如此，驱动貌似还是没有安装成功。在网上各种找解释，发现有这样的一篇文章，我就按照他的试了一下。http://e2e.ti.com/support/microcontrollers/c2000/f/171/t/311714
然而还是不行，我就很无奈了。再一次把软件卸载了，等待下一次安装。后来在网上看到，安装时不能开杀毒软件，如果有组件安装不了的情况，可以管理员运行。好吧，我再试了一次，惊喜！成功了！
