linux下使用usb设备实战（ubuntu8.10下使用移动硬盘u盘等设备）

linux下使用usb设备实战（ubuntu8.10下使用移动硬盘u盘等设备）

1：将u盘插入usb口
2：查看系统列出的usb设备
zmq@ubuntu:~$ sudo lsusb
Bus 005 Device 002: ID 058f:6387 Alcor Micro Corp. Transcend JetFlash Flash Drive
Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

3：查看内核中用来表示u盘的设备文件，下例中粗体显示系统使用sdb1来表示u盘
zmq@ubuntu:~$ sudo tail -n 20 /var/log/messages | grep kernel

4：创建挂载点
zmq@ubuntu:~$ sudo mkdir /mnt/usb


5：安装u盘
zmq@ubuntu:~$ sudo mount /dev/sdb1 /mnt/usb

6：确认安装成功
zmq@ubuntu:~$ ls /mnt/usb
Autorun.inf Recycled

zmq@ubuntu:~$ df
