Windows 8 Issue

[brburnette]

I purchased a Sabrent USB-3HDM on Friday. Hooked it up to my Samsung np700z5c with Windows 8 Pro and everything worked fine all day. Then today it doesn't work. I installed the latest DisplayLink drivers and updated my NVidia drivers. The DisplayLink support tool says it can't find any devices connected. I've tried to uninstall/reinstall drivers many times. I've attached the logs from the support tool.

Help please, thanks.
