It's great to see this function working properly at last :-)

Thanks for the video, is that a special software? Then of course one has to find or try and make the special cable.

There may be other bugs in this earlier version too, perhaps the PSE bug is the lesser evil. I suppose HP didn't want to release a patch because they would have to deal with people having fried their devices, or simply because it wasn't worth the cost.
