[PUSB] Made getDescriptor() and setup() more flexible

Alternatively we can only pass the wIndex to getDescriptor but I suggest to just pass the pointer aka reference of the whole setup.
In guess (havent tested this) that this results in more or less the code size but its a) idential with the other functions and b) we late have more flexibility here.
The Code got a quick SerialKeyboard.ino test
