It does work I am running Hardware mode on my X-keys USB. I did not use the software they suggested though it was just too dang inefficient. The way you keymap with SplatIOC is painful at best. MWIIConvert was handy for forcing the board into hardware or software mode. This is all beta and I had more than a few crashes.

When faced with having to input each keymap back in I found a better solution. I downloaded mwii.beta.05.08.07 directly from the site not from the link I gave earlier that was for another software.

the beta version of Macroii looks just like the old one. While my board was still in hardware mod I turned on the programming button, started mwiibeta which switched the board back to software mode. I loaded the keymap I created when i first got the board and under the File menu option under Advanced I selected Write. This writes the layout directly to the board and sets it back in hardware mode. I crashed several times doing this and am glad i backed up my old keymap config. During one of the crashes my orginal keymap got corrupted. So please keep in mind that this is all beta and buggy but once I got mine working its been smooth sailing.
