where the hell did my scanner go? [solved]

[dirtbag]

hey folks, i upgraded my kernel from 2.6.26-gentoo-r3 to 2.6.31-gentoo-r6
and im having problems getting my usb scanner to work..

beast jason # scanimage -L
device `brother3:bus1;dev1' is a Brother MFC-7340 USB scanner
beast jason #
but this isnt right (anymore) it seems

the gentoo wiki is actually not too bad, googling for "gentoo <whatever problem you have>" usually turns right up. The pages aren't always that up-to-date though..

I cant figure out what he did to make it work from that link.. my sane seems "stuck" on using bus1;dev1 when it should not.

-db

aha! after more investigations..

open("/dev/bus/usb/002/029", O_RDWR) = -1 EACCES (Permission denied)

(btw, the scanner moved to 029 after i removed it and replugged it into the usb hub.
so

jason@beast /dev/bus/usb/002 $ ls -al
total 0
drwxr-xr-x 2 root root 140 Feb 3 22:13 .
drwxr-xr-x 4 root root 80 Dec 20 13:17 ..
crw-rw-r-- 1 root usb 189, 128 Feb 3 22:08 001
crw-rw-r-- 1 root usb 189, 129 Dec 20 13:17 002
crw-rw-r-- 1 root usb 189, 130 Feb 3 22:08 003
crw-rw-r-- 1 root usb 189, 131 Feb 3 22:08 004
crw-rw-r-- 1 root lp 189, 156 Feb 6 14:54 029
jason@beast /dev/bus/usb/002 $


so somehow lp is now the group to be in to access my scanner..

after I put myself in the lp group and relogged in, I can now run xsane fine now.

-db

Ah thanks. I was unable to see my scanner as a normal user (only as root). then i added myself to the lp group and now I can see it.
