Send signals over USB using cocoa?

Question

Just wondering, is there any "API" for sending signals through a USB cable to a device using Apple's cocoa programming language, so I could incorporate it with an app?

is it much more complicated than a couple of commands, or do i need a library?

I have no experience with external device communication so any help is welcomed!

Answer 1

You will need to read up on IOKit to do USB on OS X. There are some cross-platform libraries like libusb that can come in handy, too. What kind of device do you want to use?
