Windows 8.1 usb disconnecting

[jordiac]

Hi all,

I'm using I'm using Kensington Display Link K33972EU and I'm having some troubles when connecting devices to the usb ports of the device.

The screen display has no issue however the devices connected to the usb ports (I tested all usb ports of Kensington device) are disconnecting randomly (sometimes twice in a minute and then they work well during 15 minutes).

This issue happens with any devices (mouse, keypad, usb memory stick).

I've downloaded the device "Windows DisplayLink support tool" and I would need your help to solve this problem (you will find attached the zip file with all the information provided by the support tool).

Thank you all!
