Hi all!
Yesterday, I tried to scan on my laptop running Kernel 2.6.4 for the
first time. Some months ago with Kernel 2.4.x scanning was no
problem. Now that scanner.o disappeared and everything is based on
libusb there seem to be problems with permissions -- but I don't
know where. Here are some information:
System:
Debian Woody (with a little bit of Sarge and Sid)
Kernel 2.6.4
libusb-0.1-4 0.1.8-8
libsane 1.0.13-4
sane 1.0.11+cvs2004
sane-utils 1.0.13-4
xsane 0.92-2
(skull = Root)
skull:~# sane-find-scanner
[...]
found USB scanner (vendor=0x055f, product=0x021d [USB Scanner],
chip=GT-6816) at libusb:002:003
[...]
skull:~# scanimage -L
device `gt68xx:libusb:002:003' is a Mustek BearPaw 2400 CU Plus
flatbed scanner
skull:~# ls -l /proc/bus/usb/002/003
-rw-rw---- 1 root scanner 50 Apr 15 11:37
/proc/bus/usb/002/003
skull:~# ls -l /dev/usb/scanner0
crw-rw---- 1 root scanner 180, 48 Mar 14 2002
/dev/usb/scanner0
(the same for all scanner*; but not relevant for libusb, right?)
chris@skull:~$mount
[...]
none on /proc/bus/usb type usbfs (rw)
chris@skull:~$groups
chris disk cdrom audio staff scanner
chris@skull:~$sane-find-scanner
[...]
# No USB scanners found. [...]
As Root everything works fine (xsane, too), so there must be a
permission problem as user. But AFAICS everything's ok with my
configuration. Did I overlook anything? -- TIA!
Best regards
