displaylink has detected other usb device software installed

[brain34]

Hi, I've been unable to install the plugable uga 165 device, due to the error above. I've searched your forums/google, and have tried all resolution options with no luck. I used to have a startech usb2vga device sometime ago, but no more. I've uninstalled the software, searched for all mct links, but I still get the error message whenever I try to run DisplayLink_7.6M1.exe.

I ran the comparability checker, which produced the attached log file. Do you mind letting me know what the issue is? thanks,
