Well done for uploading those files. Thanks.
I am still trying to get some sense out of Logi support as to why the various drivers are no longer available on their website (apart from the MSFSPlugin one). Maybe the 313 plugin incorporates the drivers, I await Logi support answer on that.
So logi got back at last and pointed out that you have to be logged-in with a Logi-ID to see the downloads.
By the way, I should have updated the OP to point out that I have everything running fine. Sorry
