無法通過macOS上的USB連接到J-Link Sierra

我最近使用macOS Sierra 10.12.4從Linux機器切換到Macbook Pro 2016。無法通過macOS上的USB連接到J-Link Sierra

當我嘗試連接到的J-Link失敗不管我使用（JLinkExe或JLinkGDBServer）具有以下錯誤，應用程序：

[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>

是絕對沒有關於J-Link在dmesg的信息。我懷疑，在我的筆記本電腦中可能存在有關USB-C端口的問題。但是，我嘗試了兩種不同的適配器，但沒有結果。在Linux上它確實工作得很好。

任何想法？謝謝。

編輯：這裏是「名爲ioreg -p IOUSB -l -w 0」縮短輸出：

我建議運行'ioreg -p IOUSB -l -w 0'來查看你的jlink是否被操作系統識別。詳細信息：http://stackoverflow.com/a/29778245/28128 –

我剛剛更新了ioreg的輸出問題。沒有J-Link的跡象。 – eclipse

我的工作了。我的J-Link電纜上的USB連接器構造糟糕，而且有些東西沒有按照應有的方式連接。我試了一個不同的USB電纜，它是確定的。
