Sporadic disconnection/reconnection (Win 8.1)

[bfrei]

Like several other users here, I have the problem that a couple of times per day, my docking station (Warpia Dock n' charge SWP240) is sporadically disconnected and then reconnected again. This happens with USB 3.0 (I do not have any USB 2.0 ports on my laptop) with Windows 8.1 64bit, all updates installed. The only USB devices hooked up to the docking station are mouse, keyboard and an HDMI display.

I have DL driver version 7.6 M2 installed.

For every disconnection, I found the following event in the event log. The vendor/device ID indicates that this is related to the installed DisplayLink devices:

Event 4, Kernel-ShimEngine
Flags [1024] were applied to device [USB:USB\VID_17E9&PID_4307] - class [USB].
Flags source: applied through compatibility database.
