Old versions of Citect dongle license, which is USB2.0 type, has compatibility issues with USB3.0 port chip driver on the new HMIs. 

There are two workarounds at this moment before a permanent fix is released: 
· Use a USB 2.0 hub for license dongle. 
· Turn off "USB Filter" in Windows Features, and reboot iPC. Connect license dongle direct to iPC. 

To turn USB Filter on or off by using Control Panel, follow directions below:
1. Click Start > Control Panel.
2. In Control Panel, click Programs and Features.
3. On the Programs and Features window, click Turn Windows features on or off.
4. In the Windows Features window, expand the Embedded Features node, and check or clear the checkbox for USB Filter.
