我正在尝试让 Native Instruments KOMPLETE Audio 1 在内核为 5.4.0-52-generic 的 Ubuntu 18.04.5 LTS 中工作。
这是一个普通的 USB2 音频接口，我将它连接到 USB3 端口。除了鼠标和键盘，没有其他任何东西连接到任何其他 USB3 端口。根据 USB3 测试仪，它在大约 450 mA 时使用 5.1 V。
虽然我之前在 Arch Linux 上使用过它，但 Ubuntu 一直在禁用该设备。为了再次使用它，我需要将其拔出并插入另一个 USB 端口。然后它会再次工作一分钟左右，直到 Ubuntu 再次禁用它。Ubuntu 有时会降低带宽并重启设备。

我尝试过更新系统包，重新启动 PC，通过内核标志禁用 IOMMU 来启动它，但这些都没有任何帮助。
是否有其他的魔法标志可以解决这个问题？
可能出了什么问题，我该如何解决这个问题？
毕竟，显然与 Ubuntu 无关。
对我来说，自从我用高质量的数据线替换了 USB 数据线后，一切都运行得很顺利（把塑料切掉一点，让它合身）。
编辑：
感谢 Jeff 的评论，我意识到在这些测试中，我总是启用幻象电源，但忘了提及。也许原来的电缆在禁用幻象电源的情况下可以正常工作。
我认为这与电流无关，因为幻象电源的电流应该很低（仅为 4 mA）。它应该在 200 mW 左右，而我的音频接口的总功耗约为 2.5 W。由于接地不当（电缆不良），我想在我的情况下，内部幻象电源可能会以某种方式干扰 USB 电路。我想知道他们是否使用开关转换器将 5 V 转换为 48 V。
