Document how to build this about espusb HOT 2 CLOSED

Hey I think I can help answer this, I got it to work by installing the esp-open-sdk and esp-iot-sdk_v1.5.1. You can follow the installation instructions from this link: https://github.com/pfalcon/esp-open-sdk
In fact, my instructions below is just from their website, except a few addition below.

I used Ubuntu 16.04, so the installation

$ sudo apt-get install make unrar autoconf automake libtool gcc g++ gperf \
    flex bison texinfo gawk ncurses-dev libexpat-dev python-dev python python-serial \
    sed git unzip bash help2man wget bzip2

Later Debian/Ubuntu versions may require:

$ sudo apt-get install libtool-bin

Create an esp8266 folder, just to be neat:

mkdir ~/esp8266/
cd ~/esp8266/

Git clone the esp-open-sdk and make it:

git clone --recursive https://github.com/pfalcon/esp-open-sdk.git
cd esp-open-sdk/
make
cd ..

Download the ESP8266 nonos sdk v1.5.1 from espressif:

wget --content-disposition "http://bbs.espressif.com/download/file.php?id=1046"
unzip ESP8266_NONOS_SDK_V1.5.1_16_01_08.zip

Git clone espusb to esp8266 folder and then modify the Makefile to your configuration:

git clone https://github.com/cnlohr/espusb.git
cd espusb
vi Makefile

EDIT: Find and change the following configuration to your settings:

GCC_FOLDER:=~/esp8266/esp-open-sdk/xtensa-lx106-elf
ESPTOOL_PY:=~/esp8266/esp-open-sdk/esptool/esptool.py
SDK:=/home/<username>/esp8266/esp_iot_sdk_v1.5.1 #Full path is needed otherwise won't compile
PORT:=/dev/ttyUSB0 #Location of your ESP8266

XTGCCLIB:=$(GCC_FOLDER)/lib/gcc/xtensa-lx106-elf/4.8.5/libgcc.a

Save & Quit

Make espusb and flash it to ESP8266:

make
make burn

Done, it should compile and burn into ESP8266 nicely.

As for hardware(Low speed configuration, 1.5Mbits)

cnlohr is working hard now to enable USB Full speed implementation (12 MBit/s), the hardware will be slightly different.

Hope this helps :) Happy hacking.

P.S I haven't tested on other versions besides esp_iot_sdk v1.5.1 and v2.0 but I did not succeed in compiling in v2.0 probably if you succeed, you can share how you did it here :D

EDIT: added gcc version change from 4.8.2 to 4.8.5 and added full path for SDK

EDIT2: SDK v1.5.4 is also okay.
