当我将 HP 1102w 打印机插入 USB 进行设置时,内核会记录一系列消息:
... kernel: [ 381.876303] usb 3-3: new full-speed USB device number 17 using xhci_hcd

因此,我无法设置这台打印机。(我之前曾通过 Wifi 使用它,但它无缘无故地停止了连接,我需要用 USB 电缆进行设置。)
我验证了多个 USB 拇指驱动器仍可在同一个端口上工作。
我的机器现在运行的是内核 4.4.0-116-generic x86_64
我在一个旧帖子中看到有人通过禁用 BIOS 中的 IO MMU 解决了类似的问题。在我的 Gigabyte 主板设置中,这被标记为“Inter Virtualization Technology”。我禁用了它,但结果没有改变。
这可能是我的 USB 驱动程序、主板或 HP 1102w 打印机的问题吗?我还能做什么来诊断它?
