本文记录了Ubuntu 12.04系统中USB设备无法自动挂载的问题及解决过程。通过安装特定驱动解决了问题，并详细描述了安装前后的系统反应。

gnome 桌面之后，貌似我的ubs设备都无法自动挂载，

vmware可以识别到，但是ubuntu12.04 /dev下看不到，也不自动弹出来。

很纠结。

切换到unity桌面，居然进去没有左边那一列程序什么的bar了。。。。。

悲剧。。

虽然无法测试是不是utiny和gnome桌面的问题，但是猜想应该没有什么必然联系，可能有简洁联系。

vmware可以识别到我插入的USB设备，但是，ubuntu12.04没有任何反应。

插入USB设备之后，还是这样：

==============================

旁边波哥的utiny桌面的ubuntu12.04就可以自动识别USB设备，难怪这方面的问题出现的非常少。

搞不懂啊。搞不懂。

=================================

于是就各种google。

安装一个usbmount。貌似不管用。

但在media目录下出现了n多个usb*的文件夹。里面都是空的。

还有建议对USB_MODEM的 http://www.draisberghof.de/usb_modeswitch/ 。

==================================

后来，

应该是这个没装吧，导致vmare无法帮助ubuntu12.04？

但是波哥的就装了么？波哥关了虚拟机了。。。未知。。。网友们谁看看自己的这个驱动是不是装了，而且也可以识别并弹出USB设备。

会自己安装。

安装之后，很神奇的关机（shutdown）是切换到（类似logout）登陆界面。

只好poweroff。

=====================================

重启，可以用了：

识别到，

root@ubuntu:/home/zhangbin#

root@ubuntu:/home/zhangbin# ls /dev | grep ttyUSB0
ttyUSB0
root@ubuntu:/home/zhangbin#

出现了USB0 和我的U盘。

=====================================

usb0可以打开U盘。

我的U盘无法直接打开。

====================================

卸载usbmount及相关软件包：
