我有 Ubuntu 16.04 64 位。我的笔记本电脑是联想 G560。这台笔记本电脑上有一个 34 毫米 minipci 插槽。我将 Renesas Minipci 插入 Usb 3.0 卡。计算机启动时它可以工作。1-2 小时后它就不工作了，我在lspci命令中看不到它。我当前的lspci命令结果如下：

如您所见，08:00.0 USB controller: Renesas Technology Corp. uPD720202 USB 3.0....这里有结果。过了一会儿，它就丢失了，我必须重新启动计算机才能使用此卡。我想重新启动或重新扫描此卡，或者一直保持工作而不重新启动计算机。我试过这些，但没有用：

请帮助我，我的默认 USB 端口有限，但对我来说不够用。我需要这张卡并一直保持工作。感谢您的回复。

我的卡坏了，所以不能正常工作。这是硬件问题。这张卡有两个端口。我买了一张新卡，它有一个端口。这张卡工作正常。我买了这张卡，这张卡工作正常：https://urun.gittigidiyor.com/bilgisayar-tablet/pcmcia-express-usb-3-0-1-ports-34mm-352673855
