Problems using latest software with Kensington Universal Docking station (sd400v)

[Brendan]

I have a Kensignton dock and have problems whenever I change the configuration of my system. Have raised this previously but cannot get a stable solution to the problem.

The unit worked perfectly up to last week, so I don't think there is an issue with cables or the unit itself.

Problem:
Unconnected - the power light on the dock blinks.
Having installed the Kensington files, then the display link update - reboot the pc and plug in the USB cable, nothng happens and the power light on the dock goes out.

Support files attached
