usb.h: No such file or directory
 

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <usb.h>

int main(int argc, char **argv){
struct usb_bus *bus;
struct usb_device *dev;
usb_init();
usb_find_busses();
usb_find_devices();
return 0;
}

I am compiling this code

gcc libusb.c -o libusb -lusb but it saying error as

usb.h: No such file or directory

Try
It's probably a matter of setting the right -I include dirs where the compiler will search for .h files.

On my system (Slackware 10.x) that is whereis usb.h

The second command will only return results if you have run updatedb at least once
