无法通过macOS上的USB连接到J-Link Sierra

我最近使用macOS Sierra 10.12.4从Linux机器切换到Macbook Pro 2016。无法通过macOS上的USB连接到J-Link Sierra

当我尝试连接到的J-Link失败不管我使用（JLinkExe或JLinkGDBServer）具有以下错误，应用程序：

[email protected]:~$ JLinkExe 
SEGGER J-Link Commander V6.14c (Compiled Mar 31 2017 17:42:24) 
DLL version V6.14c, compiled Mar 31 2017 17:42:10 

Connecting to J-Link via USB...FAILED: Can not connect to J-Link via USB. 
J-Link>

是绝对没有关于J-Link在dmesg的信息。我怀疑，在我的笔记本电脑中可能存在有关USB-C端口的问题。但是，我尝试了两种不同的适配器，但没有结果。在Linux上它确实工作得很好。

任何想法？谢谢。

我建议运行'ioreg -p IOUSB -l -w 0'来查看你的jlink是否被操作系统识别。详细信息：http://stackoverflow.com/a/29778245/28128 –

我刚刚更新了ioreg的输出问题。没有J-Link的迹象。 – eclipse

我的工作了。我的J-Link电缆上的USB连接器构造糟糕，而且有些东西没有按照应有的方式连接。我试了一个不同的USB电缆，它是确定的。
