USB 3 vs USB 2 causes screen flickering

[kirby001]

I have a Sony VAIO running Win 8 (64 bit). I got an AOC E1659Fwu, I installed the displaylink software (7.4) - plugging the AOC display into a USB 2.0 port on the Vaio. It works fine. I then switch the display to one of the USB 3.0 ports and the reusult is that the AOC screen and the VAIO screen flash on and off continuously. Once I switch back to USB 2.0, everything is fine again. I am thinking about getting a second AOC and would have to use a USB 3.0 port for the second one. So, I want to solve this problem before I do.

I did the following. 1) with the AOC Plugged into the USB 2.0 port, I used the Displaylink Debug Tool to 1) do the system compatibility check (all was OK) 2) did "Gather Information" and 3) turned on Advanced logging then ...
4) Plugged the AOC monitor into a USB 3.0 port. I let the flickering go on for 3 or 4 cycles then replugged it into the USB 2.0 port and created the debug zip file. (attached)

Please review and let me know if you have any suggestions as to how to get the USB 3.0 port connection to work.
