無法安裝 USB 隨身碟

我有一個從油炸機收到的閃存驅動器，用於複製文件。我們無法讓它連接到任何電腦。 Ubuntu 在 lsusb 上顯示它。

「我們無法讓它連接到任何電腦」聽起來 USB 幾乎已經失效了。

lsblk但是 linux/Ubuntu 上有沒有從或sudo blkid或顯示任何內容sudo fdisk -l？如果沒有關於USB的訊息，那就是一個很大的危險信號，表示它已經死了。

插入後，其中的訊息dmesg或文件/var/log/（例如）是什麼？/var/log/syslog應該有一些關於「新 USB 裝置」的訊息，然後如果它能夠在不久之後傳達包含類似「/dev/sdc」（或 sda、sdd，可能是 hdb、hdc...）之類的訊息。但隨後它應該顯示為lsblk或blkid
