Linux libusb 安裝及簡單使用

                            Linux libusb 安裝及簡單使用

一、參考文檔：
    1. libusb1 fails do_configure task with “udev support requested but libudev not installed”
        http://stackoverflow.com/questions/23712859/libusb1-fails-do-configure-task-with-udev-support-requested-but-libudev-not-ins
    2. libusb compilation error on slackware 14
        http://stackoverflow.com/questions/29552267/libusb-compilation-error-on-slackware-14
    3. Jan Axelson's Generic HID example under Linux with libusb

    4. Slackware- usb library
        http://www.linuxquestions.org/questions/slackware-14/slackware-usb-library-4175475048/

二、下載libusb：
    1. 網址：http://www.libusb.org/
    2. 下載：libusb-1.0.9，跳轉到解壓，並安裝：
        ./configure && make && make install； 
    3. 下載：libusb-compat-0.1.4，跳轉到解壓，並安裝(一定要安裝，否則總是報各種錯，本人用的是64位系統)：
        ./configure && make && make install； 

三、libusb安裝錯誤：
    1. 錯誤提示：
        checking for inline... inline
        checking operating system... Linux
        checking for library containing clock_gettime... -lrt
        checking libudev.h usability... no
        checking libudev.h presence... no
        checking for libudev.h... no
        configure: error: "udev support requested but libudev not installed"
    2. 解決方法：
        sudo apt-get install libudev-dev
