i installed the D3100 dock on my XPS 13 and everything works fine, until i had some kind of update on windows10. After this, windows shows the message "display link core software is not available anymore on your pc". I've updated the driver, re-installed the displaylink driver, but since that upgrade, the mouse and the keyboard started to lag in a pretty buggy way.
If i use the laptop without the dock everything works fine.
I'm using Dell wireless mouse+keypad.
the problem is the Dell USB3.0 dock D3100. Try to find the latest sotware relese even through other del''s websistes (ie: .com, .co.uk. etc).
