Subject: [gentoo-user] USB scanner (Canon LiDE 25) only recognized as root

1 Hi,
2
3 my Canon LiDE 25 scanner is only recognized by scanimage when logged in
4 as root.
5
6 I have:
7 kernel 2.6.15-rc7 vanilla, udev 079, libusb 0.1.10a, sane-backends
8 1.0.17, xsane 0.98a-r1, sane-frontends 1.0.14.
9
10 My user is in the usb and scanner groups, and my USE flags contain usb
11 and scanner as well.
12
13 Permissions in /proc/bus/usb are set correctly when the scanner is
14 plugged in:
15
16 cf@sakura ~ $ sane-find-scanner -q
17 found USB scanner (vendor=0x04a9 [Canon], product=0x2220 [CanoScan],
18 chip=LM9832/3) at libusb:004:011
19
20 cf@sakura ~ $ ls -l /proc/bus/usb/004
21 total 0
22 -rw-rw-r-- 1 root usb 43 8. Jan 09:59 001
23 -rw-rw---- 1 root scanner 57 8. Jan 09:59 011
24
25 And I have a /var/lib/lock/sane directory, as required by the plustek
26 backend:
27
28 sakura linux # ls -l /var/lib/lock/
29 total 4
30 drwxrwx--- 2 root scanner 4096 7. Jan 12:39 sane
31
32 And still, scanimage cannot find the scanner as user:
33
34 cf@sakura ~ $ scanimage -L
35
36 No scanners were identified. If you were expecting something different,
37 check that the scanner is plugged in, turned on and detected by the
38 sane-find-scanner tool (if appropriate). Please read the documentation
39 which came with this software (README, FAQ, manpages).
40
41 Whereas as root, it gives:
42
43 sakura linux # scanimage -L
44 device `plustek:libusb:004:011' is a Canon LiDE25 USB flatbed scanner
45
46 So what's missing here? How can I get it to work when logged in as user?
47 Do other LiDE owners experience the same problem?
48
