我使用 Linux 系统上的 USB Stick 格式化程序格式化 USB 棒（Kingston DataTraveler）。一切似乎都成功了，但现在当我插入它时，它不再被识别。我试过多台电脑。
它出现在dmesg：
[14453.736097] usb 3-2: new high-speed USB device number 14 using xhci_hcd

并且lsusb：
Bus 004 Device 008: ID 0951:1666 Kingston Technology DataTraveler G4
但在 中却没有sudo fdisk -l，它只显示我的硬盘。我能找到的其他所有内容中都显示了 USB 记忆棒fdisk——然后我知道如何使用gparted或任何其他方式重新格式化；但在这种情况下，它没有显示在 中gparted。
/var/log/syslog 的输出是：

但它并没有完全消失，因为它出现在dmesg并且lsusb——那么，问题出在哪里？
