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:

I 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.

I don't think the hardware details are integrated into the file-system, they're maintained by the USB controller

check with lsusb

also dmesg after plugging the device
