说明：  libusb，下载安装。 整个过程多次需要root权限，可通过命令sudo -s一次性取得root权限： root@jelline:~/Downloads# tar jxvf libusb-1.0.8.tar.bz2 root@jelline:~/Downloads# cd libusb-1.0.8/ root@jelline:~/Downloads/libusb-1.0.8# ./configure root@jelline:~/Downloads/libusb-1.0.8# make root@jelline:~/Downloads/libusb-1.0.8# make install
(libusb for ubuntu linux OS, you gotta use root user to install the files)
