usb.h is missing

[dotnetCarpenter]

In libibooter.h#L4 is referenced but it's not part of an installed lib.

#include <usb.h>

I got the following compilers installed:

In the readme.txt it says:

To run the ZiPhone linux binary make sure the package libusb is installed.

I got the following libusb named programs installed:
