Having read much on setting up a scanner, its embarrassing that I
cannot get it to work.
I have an Epson 3490 Photo printer attached via the usb bus to debian
sarge. I'm running kernel 2.6.8-2-686, which means I'm using libusb
rather than the kernel's scanner module ($ lsmod | grep scanner
returns nothing).
This scanner is seen on the usb bus:
$ cat /proc/bus/usb/devices | more
T: Bus=02 Lev=02 Prnt=02 Port=02 Cnt=01 Dev#= 23 Spd=480
MxCh= 0
D: Ver= 2.00 Cls=ff(vend.) Sub=ff Prot=ff MxPS=64 #Cfgs= 1
P: Vendor=04b8 ProdID=0122 Rev= 1.10
S: Manufacturer=EPSON
S: Product=EPSON Scanner
C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr=100mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff
Driver=(none)
E: Ad=81(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=83(I) Atr=03(Int.) MxPS= 8 Ivl=4096ms
The scanner is known to my backend (sane database of scanners):
$ sane-find-scanner
# sane-find-scanner
...
found USB scanner (vendor=0x04b8 [EPSON], product=0x0122
[EPSON Scanner]) at libusb:002:023
In /etc/sane.d/epson.conf there is a "usb" line (but also a "scsi
EPSON" line, which I assume is ignored.)
I have a scanner group and a saned group, and both user and root
belong to them, and I subsequently relogged in (there may be a bit of
overkill here).
scanner:x:110:root,brownh,admin
saned:x:111:root,brownh,admin
I gave permission to the scanner group to use the scanner interface:
$ ls -l /dev/usb/ | grep scanner0
crw-rw-rw- 1 root scanner 180, 48 2005-09-08 12:16 scanner0
And finally, for both root and user:
# scanimage -L
No scanners were identified. ...
I don't find any .usermap for scanning in /etc/hotplug/usb/, nor is
there any usb.usermap file. Not sure there should be. The closest is
/etc/hotplug/usb.handmap, but it has no entry for a scanner. I assume
that hotplug is irrelevant here.
