Please help. Thanks in advance.

Please try this:

  • run dmesg or lsusb and find the idVendor and idProduct for the appropriate hikey960 connection
  • add the line below to /etc/udev/rules.d/51-android.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="idVendor from dmesg or lsusb", ATTR{idProduct}=="idProduct from dmesg or lsusb", MODE="0600", OWNER="your username"
  • adb kill-server
  • adb start-server
  • adb devices

If it doesn’t work, then you’re stuck with using adb over tcpip. See the 2nd item under for details.
