How to install libusb?
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 new users make.
Then 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
