So what do you include? usb_ch9.h I guess. And the message says that you should not do that but that you should Usb.h instead.

Can't be much clearer :wink:

You should also learn to post your code (using code tags; see one of the stickies how to do that) when you encounter code / compiler problems. It would take the guessing out in the beginning of this reply.

And maybe post a link to the library so we do not have to search (and possibly find a slightly different one from what you use).
