在Ubuntu中使用Jlink出现问题

确认J-Link在windows下工作良好能运行JLinkExe和JLinkGDBsever，然后在新的ubuntu发行版上运行./JLinkExe会出现
root@zullge-virtual-machine:/opt/SEGGER/JLink# ./JLinkExe
SEGGER J-Link Commander V4.94h ('?' for help)
Compiled Nov 28 2014 17:54:18
Can not connect to J-Link via USB.

查看USB挂载情况如下
root@zullge-virtual-machine:/opt/SEGGER/JLink# lsusb
Bus 002 Device 005: ID 1366:0102 SEGGER
Bus 002 Device 004: ID 0e0f:0008 VMware, Inc.
Bus 002 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
可以看到segger Jlink 已经挂载。
使用Jlink的命令帮助：
J-Link>ShowEmuList
J-Link[0]: Connection: USB, Serial number: 123456, ProductName: J-Link
J-Link>
于是看到JLINK的USB串口号为123456
继续使用USB命令如下：
J-Link>usb 123456
Connecting to J-Link via USB (Port: 123456)
Emulator with USB serial number 123456 selected.

发现这个我在win7下直接运行JLinkExe的如果一致说明在Ubuntu下是已经Jlink连接到我的6410目标板了。
但为什么我在Ubuntu下直接运行./JLinkExe 会连不上，运行./JLinkGDBsever
出现如下结果：
