Sorry about the silence! I was laid up in hospital for a while and I'm still way behind on pretty much all parts of life, but doing my best to catch up.
The situation with the LeoStick drivers became really confusing with the release of Arduino IDE v1.0.1 unfortunately, which totally changed the Leonardo board profile compared to v1.0, and also with changes to the bootloader used on the Leonardo and compatible boards including the LeoStick. The early Leonardo bootloader that was made available during the beta period was called the "Diskloader" bootloader, and that's what IDE v1.0 expects to see. The Diskloader bootloader is what we shipped on the first couple of thousand LeoSticks.
However, when the final Leonardo was released and IDE v1.0.1 came out to match it, the board profile was different and it used a new bootloader called "Caterina".
Result: confusion.
But never fear, it's all sorted out now!
To clear things up I've just finished a major rewrite of the LeoStick setup guide, created two revised board profiles to cover the different bootloaders, and created a new unified .inf file (only required on Windows) that combines all existing Freetronics boards (including both LeoStick bootloaders) into a single file to make installation much simpler.
Hopefully this'll help you out, so please check out the updated guide:
