I have exactly the same issue. I am using Lenovo USB 3.0 docking station (2x DVI, Gb Ethernet, 5x USB 3.0 hub) with latest firmware on Samsung 780z5e and I had the issue with 7.4M2 and also I have it now with 7.5M0. I am running windows 8.1 x64. It seems that there is some infinite loop which is doing something with the registry. According to Task Manager, the DisplayLinkManager.exe did 85k writes (I/O writes), writing around 5GB (I/O write bytes) of data over period of just 10 minutes.

Please find attached screenshot from process manager and also attached support information from your tool. Many thanks for your kind support.

P.S.: is is possible that these writes are related to the USB device rather than to disk writes?
