如何通过查看 debugfs 输出来获取 USB 驱动器的最大信息?

如何通过查看 debugfs 输出来获取 USB 驱动器的最大信息?

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
