Hi!
I couple of months ago I made a post asking about the compatibility of the Vortex Pok3r RGB with the XIM Apex, a mod told me that powering the XIM could help and indeed it did! Thank you so much, it works now!
I made this post so the keyboard can be taken off the incompatibility list or edited to add that it just needs a power cable to work. I wouldn't want people to think they can't use this keyboard because it's honestly an amazing keyboard.
