When will HOTAS support be added on GOG?
According to the Steam forums, the 1.1.1. patch would add this.
When will this 1.1.1. update be available on GOG?

Patch 1.1.0 added HOTAS support already, 1.1.1 fixed some issues related to that and will be up soon!

Thanks for the reply.
Could you please explain to me then, how to setup the Logitech Saitek X52 pro (without pedals) with Everspace?
When I customize the controls in Everspace, it doesn't seem to recognize any of the input of the x52.
Is there a special profile I need to load in the X52 control application?

Edit:
I've followed your suggestion on the steam forum and started the 64bit version directly.

The x52 is now detected and I can assign its buttons and axes, but I can't apply, because now the input method constantly switches between mouse and hotas......
And this problem now persists after restarting the game. I can't even click any menu item now with the mouse....

These issues were fixed by the 1.1.1 update, which we hope will be on GoG soon! We submitted the update to GoG but they haven't added it yet unfortunately.

It's working now in the 1.1.2 update on Gog. Thanks!
