Como montei a unidade de CDROM USB

Question

Eu tenho um drive de cdrom usb externo, mas não consigo encontrá-lo no RHEL 7.4. A imagem anexada é o resultado do meu "ls / dev /".

Quandoexecutoo"cat / var / log / dmesg | grep usb", obtenho os resultados abaixo, mas não vejo em qual arquivo dev ele está, para que eu possa montá-lo.
