I inserted an usb into my Fedora 11 PC.Gave a mount command and the output was as shown below: /dev/sdc1 on /media/8d079aad-038c-4667-9186-e21bed0928d5 type ext2 (rw,nosuid,nodev,uhelper=devkit)  Now i gave debugfs /dev/sdc1 and the output is as shown below:  [root@Android04 Android-STB-Source]# debugfs /dev/sdc1debugfs 1.41.4 (27-Jan-2009)debugfs:  statsFilesystem volume name:   <none>Last

directoriesI would like to get the maximum info (info i can get from giving lspci) from this printed info. I would like to know how i can do that. What i have in my mind is like, I give a command :  dd bs=<some size> skip=<some size> count=1 if=/dev/sdc1 | od -Ax -tx1z -v   And this shows the needed details. Basically i need to get the USB hardware details form the filesystem.Please suggest on this idea, or if you have some other idea for doing the same.
How to get the maximum info for a USB drive by looking at the debugfs output?
usb;mount
