Displaylink will not recognize USB adapter

[tcc421]

I have an HP USB Graphics Adapter that is having a hard time being recognized by the displaylink software. First of all, I have a Dell Optiplex 760 and the displaylink user interface will only recognize it with version 5.6.31854. I have an Optiplex 790 where I have to uninstall/reinstall/reboot/disconnect the device/change software versions for 2 hours to get the software to recognize it. However, once the device is disconnected or the computer restarted I have to do the same things over and over again. I once even got the optiplex 790 working again by running the Displaylink support tool. I even tried on an optiplex 780 and I am having the same issues as the 790. I have included the log files from the 780 for some assistance.
