我有一个新的 USB 驱动器，插入计算机后可以工作一两次，但现在不知何故它完全没有响应。我想弄清楚这是硬件故障，还是设备上的分区出了问题。
没有创建分区或驱动器（/dev/sdc 不存在，/dev/sdc1 等也不存在，所有其他 /dev/sdx 设备都是我所知道的）。
该设备根本没有出现在 lsusb 中，当我插入设备时，我收到以下 dmesg 输出：

我也尝试将驱动器插入 Windows 机器，但没有成功（Windows 告诉我设备未被识别）。我还能尝试其他什么来恢复设备吗，还是它完全无法恢复？
我发现这链接表明这可能与硬件过流保护有关，但我尝试了他们的建议，关闭/等待几分钟，以及几分钟不使用该设备。我电脑上的 USB 端口可以与其他驱动器（甚至是另一个相同型号的驱动器）一起使用，只有这一个驱动器导致问题。
我想要保留的驱动器上没有重要数据；我只是想避免更换物理驱动器。
