Only USBHost library is under GPL. Since the original USBHost is licensed under GPL, we are forced to release that part under GPL.

The remaining part of Arduino core is under the less restrictive LPGL.

So, if an Arduino developer simply deletes the USBHost library, in subsequent development he/she is bound by LGPL only, and not anything stronger?

I thought the tricky (and controversial) thing about GPL 2 was that if you used it anywhere in your project, then your whole project falls under the licence conditions. So, everyone is certain that having _some_ GPL 2 licensed code as part of the standard Arduino 1.5 distro doesn't have a knock-on effect that means _everything_ in Auduino 1.5 is now GPL 2?

That could lead to some "uh-oh" moments... always best to be 100% clear about such issues at the outset of any development effort.

pico, are you sure? this is a major point to be cleared.
If what you are saying is true, the USBHost lib should be deployed as a separate download ASAP.

No, not at all. That's why I was asking the question!

Agreed.

That would seem a prudent course of action.
