[ubuntu] How to install libusb in Ubuntu

Here is what worked for me.

Install the userspace USB programming library development files

sudo apt-get install libusb-1.0-0-dev
sudo updatedb && locate libusb.h

The path should appear as (or similar)

/usr/include/libusb-1.0/libusb.h

Include the header to your C code

#include <libusb-1.0/libusb.h>

Compile your C file

gcc -o example example.c -lusb-1.0
