Eu não acho que os detalhes do hardware estejam integrados no sistema de arquivos, eles são mantidos pelo controlador USB
Eu inseri um usb no meu Fedora 11 PC.
Deu um comando mount e a saída foi como mostrado abaixo:
/dev/sdc1 on /media/8d079aad-038c-4667-9186-e21bed0928d5 type ext2 (rw,nosuid,nodev,uhelper=devkit)
Agora eu dei debugfs /dev/sdc1 e a saída é como mostrado abaixo:

Gostaria de obter a informação máxima (informações que posso obter de dar lspci ) a partir desta informação impressa. Eu gostaria de saber como posso fazer isso.
O que eu tenho em mente é que, eu dou um comando:
dd bs=<some size> skip=<some size> count=1 if=/dev/sdc1 | od -Ax -tx1z -v
E isso mostra os detalhes necessários. Basicamente eu preciso obter os detalhes do hardware USB do sistema de arquivos.
Por favor, sugira sobre esta ideia, ou se você tiver alguma outra ideia para fazer o mesmo.
Eu não acho que os detalhes do hardware estejam integrados no sistema de arquivos, eles são mantidos pelo controlador USB
verifique com lsusb
também dmesg depois de ligar o dispositivo
