我将 USB 插入我的 Fedora 11 PC。
给出mount命令，输出如下所示：
/dev/sdc1 on /media/8d079aad-038c-4667-9186-e21bed0928d5 type ext2 (rw,nosuid,nodev,uhelper=devkit)
现在我给出了debugfs /dev/sdc1输出，如下所示：

我想lspci从这个打印的信息中获得最大的信息（我可以从给予中获得的信息）。我想知道我该怎么做。
我心里的想法是，我发出命令：
dd bs=<some size> skip=<some size> count=1 if=/dev/sdc1 | od -Ax -tx1z -v
这显示了所需的详细信息。基本上我需要从文件系统获取 USB 硬件详细信息。
请提出这个想法，或者如果您有其他想法来做同样的事情。
答案1
我不认为硬件细节被集成到文件系统中，它们是由 USB 控制器维护的
答案2
检查与lsusb
插入设备后也会显示 dmesg
