USB 驱动器“不是块设备”

我在 System76 Galago 上运行 Artix Linux。当我插入 USB 设备时，它显示为 /dev/usb/003/00X。

lsusb 输出示例：

Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 5986:9102 Acer, Inc BisonCam,NB Pro
Bus 003 Device 002: ID 05dc:a815 Lexar Media, Inc. JumpDrive V10
Bus 003 Device 004: ID 8087:0026 Intel Corp.
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

并且安装起来遇到很多麻烦。

sudo mount /dev/usb/003/002=mount: /mnt: /dev/bus/usb/003/002 is not a block device.

sudo fdisk /dev/bus/usb/003/002=fdisk: cannot open /ddev/bus/usb/003/002: Operation not permitted

sudo cfdisk /dev/bus/usb/003/002 /mnt=cfdisk: cannot open /dev/bus/usb/003/002: Inappropriate ioctl for device

sudo parted /dev/bus/usb/003/002= ``` 错误：设备 /dev/bus/usb/003/002 太小，无法存储文件系统或分区表。也许您选择了错误的设备？警告：同步/关闭 /dev/bus/usb/003/002 时出错：参数无效


This is a flash drive that, to the best of my knowledge, has a FAT filesystem with backups.

答案1

你的/dev/bus/usb/003/002是USB接口的代表。它不是该闪存驱动器上内容的表示（如果它是闪存驱动器）。你无法安装它。

dmesg插入闪存驱动器后查看一下。您应该看到类似的内容

在这种情况下，/dev/sdh1或者/dev/sdh2是您要安装的设备。 （是的，该闪存驱动器有两个分区，因为我需要两个分区）。

如果你想通过 USB 路径来识别分区，你可以使用 中的别名/dev/disk/by-path/。或者 中的任何其他别名/dev/disk/by-*，如果您想通过卷标或其他方式识别它。
