我有两个相同的 USB/MP3 播放器。其中一个已损坏（未卸载就移除）。我想通过克隆正常工作的设备来修复损坏的设备。
损坏的设备在 /var/log/messages 中报告此情况

工作设备正确安装在：/run/user/1000/gvfs/mtp:host=%5Busb%3A002%2C026%5D/
腐败者当然不会这么做。
我原本打算使用日进行逐位复制，但无法弄清楚如何在 /dev/ 中找到设备编号，就像传统硬盘或 USB 一样。
有人可以建议一些步骤吗？
更新：尝试 2（使用较旧的 Linux 内核作为 USB 存储安装）：
读完本文后关于作为 MMS 而不是 MTP 安装的文章，当我插入设备时，出现了以下信息：

我使用 dd if=/dev/sdb of=/tmp/walkman.clone 来克隆驱动器
当我连接损坏的设备时，出现了以下情况：

不幸的是： dd if=/tmp/walkman.clone of=/dev/sdb 导致
dd: opening `/dev/sdb': No medium found
cfdisk /dev/sbd 也声称未找到媒体
