[RH 7.2] HP 4100c scanner

[a casema user]

Ik probeer mijn scanner (HP 4100c te installeren onder RedHat 7.2) en volgends de site van SANE wordt mijn scanner ondersteund.
Maar bij het opstarten van het programma krijg ik de melding dat er geen scanner gevonden is.

Op een site heb ik daarover wat uitleg gevonden.

* My scanner works with USB on Windows. But not with Linux.
First be sure that the scanner is found by the system. Do the following steps as user root.
To get a listing of the devices found on the USB do

cat /proc/bus/usb/devices

This gives you listings similar to the following:

T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 1.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=03f0 ProdID=0601 Rev= 1.00
S: Product=HP ScanJet 6300C
S: SerialNumber=SG98P161P3PE
C:* #Ifs= 1 Cfg#= 1 Atr=60 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=00(>ifc ) Sub=00 Prot=00 Driver=usbscanner
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 16 Ivl= 0ms
E: Ad=83(I) Atr=03(Int.) MxPS= 1 Ivl=250ms

zoiets heb ik ook , tot dusver goed

The entry "Product=" should show your type of scanner. If you don't find an entry for your scanner, it is not recognized. Check if your kernel supports USB and if you have installed the necessary packages.
Now when your scanner is recognized, do a

cat /proc/bus/usb/drivers

This should give you something like

usbdevfs
hub
hid
48- 63: usbscanner

jaaaaa, ook nog goed.

This indicates that the usbscanner driver is available. Now have a look at the permissions of the device /dev/usbscanner by

ls -l /dev/usbscanner

If it shows

crw-r--r-- 1 root root 180, 48 Jan 19 2001 /dev/usbscanner

nee
dat bestaat dus helaas niet bij mij

it is not ok. Only root can read and write to the scanner. To allow everyone to use it, do

chmod 666 /dev/usbscanner

Now look where the configuration file hp.conf of SANE is located. It should be at /etc/sane.d/hp.conf or /usr/local/etc/sane.d/hp.conf. To that file you need to add the two lines

/dev/usbscanner
option connect-device

The file then should look like

scsi HP
/dev/scanner
/dev/usbscanner
option connect-device

You might need to use /dev/usb/scanner0 instead of /dev/usbscanner.
Now you should be able to use the scanner with SANE.

bij het opstarten kreeg ik ook wat output van usb in mijn /var/log/messages file (een selectie daarvan)

Niets Je mist gewoon het device voor je scanner.

Doe eens:

mknod /dev/usbscanner c 180 48

Dan maakt'ie /dev/usbscanner aan voor je.

dank je.
Het werkt nu idd, jammer dat ik niet eerder ergens anders kon lezen hoe dit verholpen kon worden.

Nu aan de slag met de webcam, wordt vast een stuk moeilijker.
