Hello!
For a while I wasn't figuring out what happened a while ago (between 2.x.1704 and 2.x.1887) which simply made gps data transfer not working with my Holux M-1000C, but yesterday I've been determined to look around the menus for new features which may have broken it and yes, there's a new device protocol called "Holux M-1000C", which was autoselected.
And it doesn't work.
Selecting old "Holux" (first option) just works.
