Tengo un USB que está protegido contra escritura:
dmesg | tail
[10098.126089] sd 7:0:0:0: [sdb] Write Protect is on

¿Cómo puedo desactivar la protección contra escritura?
Lo que he intentado
- Comprobado si tiene un interruptor de hardware: no
- Intenté formatearlo en Windows y en Linux (también a través de la terminal)
- Probado
fdisk
|chmod
- Intenté solucionar esto con varias herramientas del centro de software de Ubuntu
- Usé Google y he visto alrededor de 10,000 discusiones sobre este problema, pero nunca se resolvieron
