How to install libusb 1.0.0 under Ubuntu?

Question

USB

I needed to build code under ubuntu that uses libusb-1.0.
I downloaded libusb-1.0-0-dev via apt-get, but only the libusb.h file was downloaded. Tried several solutions - none of them work.
The code's Makefile contains this:
...
CFLAGS=-O3 -g -std=c99 -W -Wall `pkg-config --cflags libusb-1.0` $(DEFINES)
LDFLAGS=`pkg-config --libs libusb-1.0 `
...
When trying to compile, it displays errors on functions from either usb.
How to properly install this libusb?

Answer 1

apt-get install libusb-1.0-0
apt-get install libusb-1.0-0-dev
pkg-config worth it?
