Android smartphone and UD3900 issues?
When I connect my android nougat device to UD3900 I get the following results

  1. USB storage attached appear on smartphone and works well
  2. USB headphone works but requires restarting UD3900 for it to be recognized
  3. USB keyboard/mouse works but requires restarting UD3900 for it to be recognized
  4. USB displaylink + monitor works with the displaylink app
  5. USB ethernet does not work. However, if I connect my android smartphone directly to a Linksys USB3GIG USB 3.0 to RJ45 Gigabit Ethernet Adapter, ethernet works well

Please if you could comment on this results
