I recently have been having the same issue with Windows 8.1. Everything worked fine with Windows 8, but then the Windows 8.1 upgrade happened and displaylink no longer functions the same way on this system. It always involves Windows sleep or shutdown. When the system goes to sleep or is shutdown, it will frequently have problems restoring the USB services upon restoration from sleep or shutdown. Since my displaylink device is connected via USB3, the USB3 connection could be the source of the problem. Others have been reporting the same issue but noticed the issue disappeared if the connector is instead reconnected to USB2. I have wasted way too many hours trying to resolve this until I did a search online and found a common issue being reported by many. USB3 +Windows 8.1 + sleep = failure.

I worked with one of your technicians to replace the displaylink and intel graphics drivers using an approved method, but the problem remains.

If you do testing of the Targus 3.0 docking station (ACP71USZP) with a Windows 8.1 device and put it to sleep for a minute or two, you should be able to replicate the issue. Up-to-date USB mice and keyboards hooked up to the docking station do not get restored.

People should not have to power cycle their docking station to get it to properly reinitialize.

Thanks!
