无法挂载 USB 驱动器

我有一个朋友给我的闪存驱动器，用来复制文件。我们无法将其连接到任何计算机。Ubuntu 在 lsusb 上显示它。

lsusb 的输出

“我们无法将其连接到任何计算机”听起来好像 USB 已经坏了。

lsblk但在或sudo blkid或 上，linux/Ubuntu 上会出现什么吗sudo fdisk -l？如果没有关于 usb 的信息，那就是 usb 坏了的危险信号。

插入时， 中的消息dmesg或文件/var/log/（如/var/log/syslog）是什么？应该有一些关于“新 USB 设备”的消息，然后如果它能够在不久之后传达包含“/dev/sdc”（或 sda、sdd，可能是 hdb、hdc...）之类的消息。但随后它应该显示lsblk或blkid
