I'm successfully using this USB host to read the keyboard inputs and have the ASCII numbers of the characters out to be converted.
It is very useful since it is integrating all the translation process of the keyboard signals and I have only to read its serial output as an ASCII character.
Anyways there are two problems.
The first problem is that this USB host controller is now sold as a kit, minimum 10 pieces, and it is very hard to be implied in a long term project, since it can be dismissed by the producer etc..
The second problem is that I don't have the full control on it since I have to flash it with its software, so again it's not reliable in a long term view, since I don't know what's going on at the board level.
Do you know any open source or arduino friendly alternative, able to read and translate USB keyboard inputs?
