well, i tried to go back on the W11 machine to the [leapmotion] setup: 

however, the controler isn't working, it doesn't show the 3 red
sensor-lights. 

re-installing the Gemini/[ultraleap] -> no problem. 

installed the [leapmotion] setup on the old W10 -> same result:
controler not working. 

changing to Gemini/[ultraleap] -> working. 

?? 

that's it for now.

But before I dig any further: are you *sure* you're clicked on Pd to make it the foreground application when testing [leapmotion]? If you're clicked on the desktop or any other window/app to lose focus, then tracking data will stop flowing. And if those focus gained/lost messages aren't making sense with the actual clicking you're doing, that's what we need to look into. Maybe I can just disable the need for focus entirely...

> Hi rolf, there are a few confusing things in the LEAP world across Linux/Mac/Windows, but when I was working on this a few months back I did successfully get both [leapmotion] and [ultraleap] working on multiple Windows 10 machines with an original Leap Motion Controller. That said, since you're on Windows 11 there could be some new wrinkles. But here are some starting points to check:

Maybe running that dpinst64.exe installer will resolve things, though I'm not too confident of that since you're already using your device successfully with other software.

The latest software supports the new UltraLeap controller as well as the original LEAP Motion Controller (which is what you seem to be using). If you install that, you can try using the [ultraleap] external instead, and hopefully things "just work." It's also available via deken.

If that's the case, you'd see messages in Pd's console warning that "The specified module could not be found." About the focus gained/lost messages, those should occur when you click on or away from Pd to make it the foreground application or not. If you're getting spammed with a bunch of these messages and aren't changing application focus, then there's an issue I should look into. That worked as expected for me in my Windows tests back in January.
