I need to install it to the folder of my C program. Otherwise, it will not work. sudo apt-get install libusb-1.0-0-dev or # apt-get install libusb-dev can not help. – Nonmetal 31/1, 2011 at 17:24

Don't understand this. You say you copied libusb to the folder of your C program and it didn't work. And now you say you need to copy it to the folder of your C program or otherwise it will not work. Can you give a more detailed description of your problem? – Hexane 1/2, 2011 at 17:8

@kayahr: thanks for reply. I did not say i need to copy it to the C program folder. I said I need to install it to the C program folder. Copy and install are different. Just like in Windows, you install MS Office to Programs folder, you do not simply copy MS Office file to Programs folder. That is what I mean. – Nonmetal 2/2, 2011 at 20:54

Can you describe what files are expected after "installation"? Do you need the libusb.so and usb.h file in the root of your C program folder? Or must it be installed into "lib" and "include" sub directories? Or any other directory structure? – Hexane 2/2, 2011 at 23:10

@kayahr: thanks for trying to help me. I actually solved my problem today. I just extract the libusb.zip file and change the directory of #include in my C program to the extracted folder. – Nonmetal 3/2, 2011 at 14:49

Usually to use the library you need to install the dev version.

Try

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

This should work:

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

I did that, and it took me through the installation dialog, but it's still not working for me. The man page isn't showing up and when I try to include libusb.h, I get "no such file or directory". – Destruct 6/9, 2012 at 19:8

This installs development support for the old version of libusb, the poster wants to install support for libusb-1.0 which has a different API. – Unaccountable 3/1, 2014 at 18:24

First,

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

updatedb && locate libusb.h.

Second, replace <libusb.h> with <libusb-1.0/libusb.h>.

update:

don't need to change any file.just add this to your Makefile.

`pkg-config libusb-1.0 --libs --cflags`

its result is that -I/usr/include/libusb-1.0 -lusb-1.0

where to add this in the Makefile? no matter where I add this, I get some Makefile errors like "missing separator" - and also do I need to use these backticks? – Phlogistic 19/12, 2020 at 19:52

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

Thanks for this! That -l flag was needed for me, otherwise "undefined reference to libusb_" functions! – Classieclassification 7/2, 2019 at 18:15

Recommended method for installing the latest libusb library on any linux system is by building it from source code.

Below are the steps to build libusb source code and install it correctly on your ubuntu system:

git clone https://github.com/libusb/libusb.git
git checkout tags/v1.0.22 -b V1.0.22
./configure --enable-udev --disable-static
make
sudo make install

Communication between a user space C program and a USB device, users can refer to the API documentation https://libusb.sourceforge.io/api-1.0/index.html

This doesn't work: bash: ./configure: No such file or directory, there is configure.ac instead. – Actinomorphic 24/7 at 17:8

"I need to install it to the folder of my C program." Why?

Include usb.h:

#include <usb.h>

and remember to add -lusb to gcc:

gcc -o example example.c -lusb

This work fine for me.

usb.h is for libusb-0.1 and is outdated. – Cherie 25/3, 2018 at 4:42

you can creat symlink to your libusb after locate it in your system :

sudo ln -s /lib/x86_64-linux-gnu/libusb-1.0.so.0 /usr/lib/libusbx-1.0.so.0.1.0 

sudo ln -s /lib/x86_64-linux-gnu/libusb-1.0.so.0 /usr/lib/libusbx-1.0.so
