Problema scanner Epson perfection V350 Photo.

[esimplex]

Buonasera a tutti, lo scanner Epson perfection V350 Photo che uso funziona, il problema è fa la ricerca del dispositivo per 2 minuti prima di essere pronto. E' normale o si può fare qualcosa per ridurre questo ritardo?
Grazie.

[Vir1966]

Quale applicazione usi per lo scanner?

[esimplex]

Hai ragione l'ho omessa, uso Xsane ma ho lo stesso ritardo con Simple Scan

Non sono un esperto e non ho quello scanner, quindi probabilmente non saprò aiutarti. Fatta la premessa, se come immagino è uno scanner usb, hai provato a cambiare porta? E i driver come li hai installati, hai già visto questa guida?
ciao

[esimplex]

Ho cambiato porta e seguito quella guida precedentemente per l'installazione, ma il risultato è rimasto uguale.

# You can do so by the following configuration command:
# 
#   usb <USB vendor ID> <USB product ID>
#
# SEIKO EPSON's USB vendor ID is '0x04b8' (without quotes).  In order
# to find the USB product ID, use lsusb(1).
# A sample configuration for the Epson Perfection 1650 (Epson GT-8200),
# which has a product ID of 0x0110, would look as follows:
#
usb 0x04b8 0x012f


# For SCSI devices not detected, you can add an entry like:
#
#   scsi EPSON GT-20000
#
# where the GT-20000 bit corresponds to the SCSI model information as

# Network attached devices may be made to work by first installing the

#
# For each network attached device, you must add an entry as follows:
#
#   net <IP-address|hostname> [port-number]
#
# Ask your network administrator for the device's IP address or check
# for yourself on the panel (if it has one).  The port-number is very
