Scanner HP Scanjet 4400c

[Gmalex]

Salve,
qualcuno sa come far funzionare sto maledetto scanner su Linux Debian SID con kernel 2.6?
Non ho mai fatto andare uno scanner su linux...ho fatto qualche giro....ho installato sane, la libusb0-1.4 e cose varie....in /dev/usb trovo:

pasqualino:/dev/usb# ls
ez0 ez2 lp0 lp2 mouse0 mouse2 rio500 scanner15 scanner9
ez1 ez3 lp1 lp3 mouse1 mouse3 scanner0 scanner2
ez10 ez4 lp10 lp4 mouse10 mouse4 scanner1 scanner3
ez11 ez5 lp11 lp5 mouse11 mouse5 scanner10 scanner4
ez12 ez6 lp12 lp6 mouse12 mouse6 scanner11 scanner5
ez13 ez7 lp13 lp7 mouse13 mouse7 scanner12 scanner6
ez14 ez8 lp14 lp8 mouse14 mouse8 scanner13 scanner7
ez15 ez9 lp15 lp9 mouse15 mouse9 scanner14 scanner8

in particolare:

pasqualino:/dev/usb# du *scanner*
0 scanner0
0 scanner1
0 scanner10
0 scanner11
0 scanner12
0 scanner13
0 scanner14
0 scanner15
0 scanner2
0 scanner3
0 scanner4
0 scanner5
0 scanner6
0 scanner7
0 scanner8
0 scanner9

provando a fare "kooka -d scanner0", "kooka -d scanner1"..."kooka -d scannerX" mi dice sempre:
"Problem: No scanner was found."
Your system does not provide a SANE (Scanner Access Now Easy), which is required by the KDE scan support.
Please install and configure SANE correctly on your system."
ma io sane l'ho installato tant'è che:

pasqualino:/dev/usb# dpkg -l sane libusbMutex destroy failure: Device or resource busy

Ho letto il man di sane, in particolare "sane.hp", che mi dice:

The following scanners are known positively
to work with this backend:

ma che devo fare?

prova a guardare su
http://www.buzzard.me.uk/jonathan/scanners-usb.html riporta un elenco di scanner riconosciuti da SANE.
Forse trovi anche qualche info che ti puo servire.

Mi spiace di non poterti aiutare di più! (io ho un HP4200c ma dopo ore e ore di tentativi, su linux non da ancora segni di vita!!)

These scanners uses a RealTek RTS8891 chip to drive the scanner. Requests for information on this chip to RealTek have gone unanswered. There is some very preliminary software for these based on reverse engineering the Windows driver. More information on this can be can be found at SourceForge here.
