CUPS: Unable to open USB device

[Harp]

Non so per quale motivo, da un paio di giorni ricevo questo errore, dalla pagina http://localhost:631/printers:
"Unable to open USB device "usb://EPSON/Stylus%20Photo%20R220": No such device"
Device URI: usb://EPSON/Stylus%20Photo%20R220

Cosa devo sistemare?

P.S. Di recente ho upgradato il kernel alla versione 2.6.16.11 e KDE 3.5.2

[Harp]

Non so se è una cosa sensata ma posto anche l'output di cat /usr/src/linux/.config | grep USB

prova a leggere il file di log, magari ti da qualche informazione in più

[l1q1d]

iniziamo così:
stacca la periferica
apri un terminale e digita (da root)

Codice: Seleziona tutto

tail -f /var/log/messages

collega la periferica e vedi che modfiche vengono fatte al log così da scoprire come te la rileva.

[samiel]

Non è che hai versioni recenti di udev?

Non ho fatto aggiornamenti particolari nell'ultima settimana.
Ma è possibile che sia capitato di punto in bianco?
Ho stampato fino a qualche giornoi fa senza problemi.

La mia versione di udev è: udev-064-i486-2

Chiedo umilmente scusa.
La stampante era semplicemente sconnessa, non so per quale motivo.
E' bastato riavviarla dalla pagina di CUPS.

Scusate ancora.
