This is how you install libusb:

sudo apt-get install libusb-1.0-0-dev

Note that if you are using libusb in a C/C++ program you should include it the following way:

#include <libusb-1.0/libusb.h>

and not like this:

#include <libusb.h>

This is a common mistake that I was making. Finally you compile like this:

g++ source.cpp `pkg-config --libs --cflags libusb-1.0`

Since you are new to linux I suggest running the below command from terminal to install libusb directly from the repository:

>sudo apt-get install libusb-1.0-0-dev

If you wish to continue with the archive you have downloaded, refer to the instructions in the below link:
