我正确安装了 ise14.7，然后尝试按照本指南安装平台电缆。所有步骤都是正确的。我的 ls usb 命令输出是这样的
$ lsusb
Bus 002 Device 022: ID 03fd:0008 Xilinx, Inc. Platform Cable USB II
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
您可以看到我的操作系统知道连接了 xilinx USB 设备并且 usbdev 正常工作。但我的电缆不工作。然后我看到影响输出说：
Active mode is BS

GUI --- …我正在 Ubuntu 2016.04.5 上安装 Petalinux_v2018.2
./petalinux-v2018.2.ir.run /opt/petalinux_2018.2/
