我运行的是 Ubuntu 64 位，刚刚安装了一台打印机，Epson Stylus NX110。每当我尝试扫描或打印时，我的电脑都会关机。我的日志中似乎没有剩余任何内容（但这没什么意义，因为如果剩余了某些内容，它可能在关机前没有时间进行磁盘同步。）
我也尝试在运行 Windows XP 的虚拟机中进行扫描。同样的问题。
从症状来看，这可能是硬件问题。但这真的很奇怪。超级用户说什么？主板坏了？电源坏了？Linux 下的 USB 驱动程序坏了？
以下是有关我的系统的一些信息：

答案1
我首先要尝试的是（如果你还没有尝试的话）使用主电源供电USB 集线器。也许打印机消耗的电量刚好足以让你的主板或 PSU 崩溃。
答案2
我发现我所有电脑上的 USB 端口并不都一样。使用哪个 USB 插槽（和端口）非常重要。如果你有现代 USB 连接，情况会更糟，比如 USB3 等。
我认为你已经检查过这不是电缆的问题，也不是扫描仪的问题？
据我所知，大多数打印机都有自检模式，独立于任何其他地方的连接。我们假设您已经检查过扫描仪打印机是否正常。
我的电脑上通常有两个 Linux 系统。通常只有 Win7 或 Linux 会崩溃。我还没有发现如何在一个硬盘上安装两个 Win7 操作系统。
