Default Keyboard and mouse lag and stuck behaviour


I have a an HP Folio 13-2000 laptop which I use which several docking stations at work (often StarTech USB3SDOCKHDV but some others too).

Since I upgraded to Windows 10, I see a strange behaviour, which I interpret as lag between the keyboard / mouse and computer. What happens:
  • The mouse pointer sometimes lags behind the movement inputs
  • Some keyboard presses are missed especially when I type a bit fast (I notice on screen that some letters don't show up)
  • Some keyboard presses are repeated, for example I type the word "display" and the word "diiiiiiiiiiiiiiiisplay" shows up.

I have looked at the http://support.displaylink.com/knowl...ncy-desktop-pi and tried several things, like uninstalling and reinstalling the latest DisplayLink software and drivers, making sure I have the latest Intel video drivers, making the min processor speed 50%, etc. but nothing works. The problem is intermittent and could be linked to high CPU usage but also happens during low CPU usage so it's a bit annoying.

Before you ask: the keyboard and mouse are plugged (USB) into the docking station, which is itself plugged into the USB3 port of the laptop.

I'd be grateful for any insights!

Many thanks

Thanks for reaching out.

Is the same behaviour observed when you connect the mouse & keyboard directly to your notebook?

Could you also post the output of this tool so I can take a look?

Hi James, I have attached the diagnostics file.
Yes, plugging the mouse or keyboard directly "solves" the issue but I only have one other USB port so I can't have both unfortunately.

Thank you,

So... It looks like this maye be solved, at leats I have not had issues for the past few hours. It looks like what helped was installing the host drivers from http://www.frescologic.com/support.php as I have a Fresco USB3 hub in my laptop, but I'm not 100% sure.

Incidentally this would go against the advice you have on this page http://support.displaylink.com/knowl...ncy-desktop-pi where you say "If you have Windows 8 or above installed then the driver is supplied and controlled by Microsoft"...
