新手求助：ubuntu server 14.04 LTS无故丢失USB设备

[hahaxiansheng]

原来用ubuntu server 13.04，挂载一个USB设备，使用两年一直正常。后来13.04不被支持更新，最近换了14.04，正常使用了几天，经常无故丢失usb设备。
主要表现是：如果usb设备能正常识别，不重启系统一直都正常，但是定时重启之后，有时候能识别，有时候不能识别，看运气。如果手动重启系统，也是有时候能识别，有时候不能识别，也一样看运气。搞不懂什么原因。
系统未安装其他软件，装完系统之后就update和upgrade就投入使用了，之前用13.04一直正常。求解。（确认硬件不存在问题，两台机上测试均如此，装完系统正常几天后出现这样的问题）
usb设备为pcsc读卡器。

谢谢回复。
看了这个文章，好像跟我的情况不一样。我的是完全不能识别usb设备。
昨晚试了下，发现不能识别usb设备的时候，拔插一下usb设备又可以识别了。这么看感觉是硬件问题，事实上硬件肯定没问题，我之前用13.04没出现这个问题，而且我换台机测试，刚装好系统也没这问题，但是用几天就开始出现这个问题。

看看 有沒有 libccid.rules 檔案
sudo ls -al /lib/udev/rules.d | grep libccid.rules

如果沒有 參見

libccid.rules是红色的

现在usb正常识别是这情况

重启之后，又找不到usb设备了
