I have a Digitus USB 3.0 Gigabit Ethernet adapter which I use for monitoring network traffic of our device in the test lab. As such, it's connected to the mirroring port of my HP-1820-8G switch.

Part of my job is to run Wireshark and capture the traffic, so I start Wireshark every day - and every day I need to re-plug that adapter in order to make it work. Otherwise it's not detected by Windows (not visible in the device manager)

What can I do to have the USB 3.0 network adapter available without re-plugging it?

Details:

  • the Digitus USB 3.0 adapter is recognized as ASIX AX88179 by Windows
  • I use Windows 7 SP1 x64
  • I have a Fujitsu Lifebook E series laptop that is placed in a docking station
  • the USB network adapter is connected to a USB 3.0 port of the docking station
  • Driver is ASIX 1.14.8.0 from 2013-12-03
  • Hardware IDs: VID 0B95, PID 1790 REV 0100
  • The built-in Windows driver update does not find a newer driver
  • I'm shutting down the PC every day in the evening and power it up in the morning. I do not use Standby or Hibernate

I have tried:

  • Updating the driver from the ASIX homepage, now using the latest Windows 7 64-bit Driver version 1.14.11.0 from 2016-04-06
  • is the device no longer detected by windows or otherwise? "not working" is pretty imprecise. – Journeyman Geek Nov 30 '16 at 8:10
  • This might be a stupid question, but have you tried looking at your laptops power-plan? Maybe it turns off the usb to save power? I've had that happen to me before.. – Bungicasse Nov 30 '16 at 8:13
  • @JourneymanGeek: it's not detected by Windows, i.e. not visible in device manager. Updated the question – Thomas Weller Nov 30 '16 at 8:42
  • @Bungicasse: I'm shutting down every day, neither standby nor hibernate. Updated the question. – Thomas Weller Nov 30 '16 at 8:42
  • If it's not powering up with the machine it can't be the power plan. Kinda tempted to suggest a hub with a physical switch for the port – Journeyman Geek Nov 30 '16 at 9:09
