I'm trying to use hardware wallet trezor.io as login agent for ssh protocol, which is quite cool idea.

According their how-to

http://doc.satoshilabs.com/trezor-apps/sshagent.html

I'm trying to proceed with instalation:

$ sudo pip install trezor_agent

but it fails with: 

hidapi/libusb/hid.c:47:20: fatal error: libusb.h: No such file or directory
#include <libusb.h>
                        ^
    compilation terminated.
    error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

I'm using ubuntu 14 lts and have no experience with python. I removed most of compilation log

The error message is very clear.

libusb.h: No such file or directory

The package have a dependecy that pip can solve. You need to install libusb first.

apt-get install libusb-1.0-0-dev

Every time you get such message no such file or directory you can check what you need to install with

dpkg -S 'missing_file"

or

apt-file list "missing_file"
