Salve,
ho fatto un po' di prove e vi allego il log messages.
1) Ho fatto il boot di un sistema e ho infilato una chiavetta USB.

is not claimed by any active driver.

2) Senza fare alcuna operazione di mount del dispositivo l'ho tolto.

Aug 4 14:21:27 sgrunt devlabel: devlabel service started/restarted
3) Ho reinserito lo stesso dispositivo nella stessa porta.

4) Fatto mount del dispositivo

Aug 4 14:27:03 sgrunt kernel: sda: sda1
5) Dopo aver fatto un ls del contenuto della chiavetta l'ho smontata e
poco dopo l'ho tolta. Come vedete oltre a dire che la disconnette da dei
messaggi d'errore.

6) Ora viene il bello. Ho inserito nella stessa porta di prima un
dispositivo diverso (un HD esterno usb da 120GB). Guardate un po' che
cosa dice.

7) Intanto continua a dare gli errori sulla chiavetta tolta prima.

8) stacco il disco esterno

Aug 4 14:34:00 sgrunt kernel: unable to read partition table
Aug 4 14:34:01 sgrunt devlabel: devlabel service started/restarted
Perchè continua a dare errori sul vecchio dispositivo ogni volta che si
fa una qualche operazione?
Mi sembra chiaro che finchè non molla il primo dispositivo non potrà
riciclare il nome del device.
