Strangely I successfully installed my Leostick at work, then when I took it home to what I thought was the same environment it wouldn't install.
Is it something to do with having a fresh Leostick? From the driver install page:
So maybe you need a fresh stick every time you go to do an install?Next up, when you upload a sketch for the first time to the board, expect Windows to ask for new drivers one last time!
It's because the sketch sends in its own USB handler which will talk to Windows most times from then on.
