Simplescan lo rileva ma quando lancio una scansione mi dice "impossibile connettersi allo scanner".
Ho provato le procedure spiegate qui:
https://askubuntu.com/questions/1107632 ... untu-18-04
ma senza risultato.
Il fatto è che a volte, cambiando ingresso usb, va per un po' poi smette
Qualche suggerimento?
Grazie!
EDIT. Aggiungo che xsane lo rileva ma dice "il dispositivo è occupato".
Aggiungo che nel notebook di mia suocera, con Ubuntu 18.04, il driver ufficiale funziona bene. Solo nel mio, con la 20.04, non vede lo scanner.
Allora nuovo aggiornamento.
Simple-scan inizialmente vede un dispositivo chiamato "CANON CANOSCAN LIDE 300", e questo non funziona.
Però a volte cambiando a caso porta usb vede anche un secondo dispositivi "ESCL LIDE 300 HTTP", e questo solitamente funziona. Dico solitamente perché di rado pure questo non funziona.
Posto il comando:
Codice: Seleziona tutto
massimo@ralf9000:~$ sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.
