I have Xcode installed. So where do I get this ? I don't see anywhere on developer.apple.com where individual header files seem to be available for download. Do I need to download an upgrade to Xcode or is it a separate download ? _______________________________________________ Do not post admin requests to the list. They will be ignored.

Are you trying to do in kernel development? If so then the header is included by <IOKit/usb/IOUSBDevice.h> If you are outside of the kernel you probably want to use the IOKit Framework equivalent header family, which is <IOKit/usb/IOUSBLib.h> Shouldn't all necessary headers be included w/Xcode by default ?
