最近MacOS Sierra 10.12.4でLinuxマシンからMacbook Pro 2016に切り替えました。MacOSでUSB経由でJ-Linkに接続できませんSierra
私はそれが私が次のエラーで（JLinkExeまたはJLinkGDBServer）を使用していますアプリに関係なく失敗したJ-リンクに接続しよう：
[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>
dmesgのでJ-リンクに関する情報は絶対にありません。私は、私のラップトップのUSB-Cポートに関するいくつかの問題があるかもしれないと思う。しかし、私は結果のない2つの異なるアダプターを試しました。 Linuxではうまくいきました。
アイデア？ありがとう。

ioreg -p IOUSB -l -w 0'を実行して、jlinkがOSによってまったく認識されているかどうかを確認することをお勧めします。詳細：http://stackoverflow.com/a/29778245/28128 –
ioregの出力で質問を更新しました。 J-Linkのサインはありません。 – eclipse
