From the screen cap in your previous post, it doesn't appear that your device is fully connected.
When I open UC, it also shows all the current settings along with which device is open.
Another question is have you signed in? Under the file menu, there's a place to sign in to your presonus account.
I wonder if that's what is preventing you from checking firmware.
Mine looks like this when I'm fully connected, and none of the choices are grayed out.
