对于vivado win10系统 JTAG cable无法识别下载程序的问题

Initially the XUP USB JTAG cable would show up in the device manager under “Programming cables” as a “Xilinx Embedded Platform USB Firmware Loader” and would not be found by the Vivado Hardware Manager. I had to right click on “Xilinx Embedded Platform USB Firmware Loader” in the device manager and click “Uinstall”. When the uninstall dialog popped up I checked the box the box that says “Delete the driver software for this device.” And then click ok. Once driver uinstall completed I disconnected the programming cable. I then launched a command prompt in administrator mode and navigated to “C:\Xilinx\Vivado\2017.4\data\xicom\cable_drivers\nt64\dlc10_win7”. Once in this directory I ran the following 4 commands:

wdreg -compat -inf %cd%\windrvr6.inf uninstall
wdreg -compat -inf %cd%\xusbdrvr.inf uninstall
wdreg -compat -inf %cd%\windrvr6.inf install
wdreg -compat -inf %cd%\xusbdrvr.inf install

After doing this I connected the cable and Windows loaded two drivers for it: a Jungo driver and a “Xilinx USB Cable” driver under the “Programming cables” section.

简单来说，就是先卸载JTAG Cable，然后拔掉JTAG Cable，然后打开命令窗口（cmd），
导向"C:\Xilinx\Vivado\2017.4\data\xicom\cable_drivers\nt64\dlc10_win7".

然后依次执行以下四条命令：
wdreg -compat -inf %cd%\windrvr6.inf uninstall
wdreg -compat -inf %cd%\xusbdrvr.inf uninstall
wdreg -compat -inf %cd%\windrvr6.inf install
wdreg -compat -inf %cd%\xusbdrvr.inf install
最后插上JTAG Cable 就可以识别了，如果还不能识别，再重新安装C:\Xilinx\Vivado\2017.4\data\xicom\cable_drivers\nt64\dlc10_win10目录下的驱动.
