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

答案1
“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
