最近，我在一家实习公司开始处理智能卡读卡器连接问题。

问题中的读取器是一个使用DUAli驱动程序的DE-620，我正在使用Ubuntu16.04。无论是在vm版本还是在安装中，USB层似乎都存在一个问题，导致了下面的dmesg输出；

只要连接好设备，它就会继续运行。下面的命令也没有显示dmesg输出中的VID和PID

这个设备在一个全合一的OpenSUSE PC和我的辅助引导Win10中工作得很好，但是在Ubuntu16.04中有这个问题。解决这个问题的尝试可以找到这里，我也尝试过不同的电缆。

在USB层中可能会发生什么会导致这种情况，以及我可以做些什么来修复这个问题？

编辑:根据注释，lspci的-nn输出如下；

编辑:问题是由于usb驱动程序在最新的内核，注释NTP相关代码修复了问题。

注释掉内核中的NTP代码修复了这个问题，很明显，由于Linux内核4中添加了规则，设备本身陷入了无限循环。
