TI中文支持网在使用CC2541DK-MINI Revision 1.0.4开发板时，套件里有个cc2540 dongle，但dongle的驱动一直没安装上，驱动安装时参考的《swru270c.pdf》，驱动文件用的是 ：C:\Texas Instruments\BLE-CC254x-1.4.2.2\Accessories\Drivers；
电脑相关软件环境：Microsoft .NET Framework 4.6.2版本，win7 64 位旗舰版系统。
所有的USB口都一样，不是USB口的问题，希望可以解答一下，谢谢。
安装时系统打印的log如下

Viki Shi：
是第一次用吗？有没有烧过固件？
如果没有，试一下用smartRFProgrammer 烧入 HostTestApp 工程，或者现成的 \BLE-CC254x 1.4.1.43908\Accessories\HexFiles\CC2540_USBdongle_HostTestRelease_All.hex

是第一次用，发现不行，于是把原来芯片里的备份出来后烧了CC2540_USBdongle_HostTestRelease_All.hex，还是不行。

如果是ghost系统可能会有问题，另外64位系统可能也不行

可能是我电脑的问题，换了台电脑可以了。
