I have a usb ethernet adapter that used to work just fine. Today I unplugged it, then deleted the corresponding network service via the dialog under "System Settings / Network".

Now when I plug the ethernet adapter back in, it does not work, even though the device still gets detected:

> system_profiler SPUSBDataType
        AX88179A:

          Product ID: 0x1790
          Vendor ID: 0x0b95  (ASIX Electronics Corporation)
          Version: 2.00
          Serial Number: 0000000000FBE2
          Speed: Up to 480 Mb/s
          Manufacturer: ASIX
          Location ID: 0x01100000 / 1
          Current Available (mA): 500
          Current Required (mA): 100
          Extra Operating Current (mA): 0

But no network service gets created for it. I also tried networksetup -detectnewhardware in the terminal, to no avail.

How can I make the device usable again?

Have you tried "Add Service" in the Network preference panel?

  • Thanks. It's a bit embarrassing, but it worked for this device. I had actually tried this before without success, but probably with a different usb ethernet device of the same kind. Will create a separate question for that issue, as I can still not add a service for that.
