Eu vi Escrever imagens em bruto com segurança para pen drives USB
No Debian, porém, não receba nada desse comando: -
[$] udevadm info -a -p $(udevadm info -q path -n /dev/sdb)|grep -iE "manufacturer|product"
[$]
Pediram-me para colocar isso como uma nova pergunta, portanto, fazendo exatamente isso: -
Eu obtenho alguma saída do udevadm se eu usar o comando monitor: -
[$] udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

Ansiosos para aprender como obter informações sobre o fabricante e o produto. ou talvez tenha sido escrito ou algo assim.
Parte do comando faz alguma coisa: -
[$] udevadm info -a -p $(udevadm info -q path -n /dev/sdb)
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Foi capaz de obter a saída necessária via lsscsi, ou seja, fabricante / produto, ou seja, Jetflash e o número do modelo. Alguém conhece mais a Alcor Micro Corporation?
Mais interessante ainda, por que esse comando não funcionou?
