AnywhereUSB/2 USB Port configuration Port is unassigned and can not choose anything

I have an AnywhereUSB/2 with the latest firmware.
But I can not assign the USB a Port.
When I go to the Web Ui -> RealPort USB -> USB Port 1 is unassigned and grayed. I am not able to chosse anything.

Thank you for helping.

The AnywhereUSB single host model 2 and 5 (different than the 5M) does not have an option to assign the port To a group, it is always group 1
