Adapter No Longer Being Recognized Since Upgrading to 2.5 Beta 1

I'm running Yosemite 10.10.5 on a 2012 Macbook Pro. I have 2 external monitors, one powered via MiniDisplay Port to DVI and the other Display Link USB to DVI. All were working perfectly until I checked and decided to install the new beta.

Since installed, the Mac no longer recognizes the USB adapter what so ever. I have tried rebooting, uninstalling, correcting permissions, reinstalling, rebooting and still nothing. I have tried reverting back to 2.4.2 and still nothing. I have switched USB ports to make sure it isn't the port and I have even connected the other monitor with my other adapter and it works flawlessly.

Please help, being down a monitor is going to kill my productivity for work.

Now what????????????
