You don't have to change the mode for /dev/usb, just remove the rules:
add path 'usb*' mode 0660
add path 'usb/*' group cups
add path 'usb/*' mode 0660
It should work but you change *all* the usb devices nodes.
I don't like it.
uscanner is gone, you can remove this :
add path 'uscanner*' group cups
add path 'uscanner*' mode 0660
If you want to use the hplip tools, the user must be able to access
the ugen devices of the printer. For this I use a group hplip
/etc/group
hplip:*:999:patrick
A rule in devd.conf to run a small script when the printer is detected
(an all-in-one HP Photosmart C4680)
attach 10 {
device-name "ugen[0-9]+";
match "vendor" "0x03f0";
match "product" "0x7411";
action "/root/sbin/ugen-hdle $device-name";
};
And the small script:
/root/sbin/ugen-hdle
#!/bin/sh
dev=`echo $1 | /usr/bin/awk 'BEGIN { } { s = substr($0, 5, 99); } END
{print s; }'`
/usr/sbin/chown cups:hplip /dev/usb/$dev.[0-9]
/bin/chmod g+rw /dev/usb/$dev.[0-9]
So I've got :
# ls -la /dev/usb/*
crw-rw---- 1 cups hplip 0, 108 28 oct 03:24 /dev/usb/2.2.0
crw-rw---- 1 cups hplip 0, 112 28 oct 03:24 /dev/usb/2.2.1
crw-rw---- 1 cups hplip 0, 113 28 oct 03:24 /dev/usb/2.2.2
crw-rw---- 1 cups hplip 0, 114 28 oct 03:24 /dev/usb/2.2.4
crw-rw---- 1 cups hplip 0, 115 28 oct 03:24 /dev/usb/2.2.5
crw-rw---- 1 cups hplip 0, 116 28 oct 03:24 /dev/usb/2.2.6
crw-rw---- 1 cups hplip 0, 117 28 oct 03:24 /dev/usb/2.2.7
crw-rw---- 1 cups hplip 0, 118 28 oct 03:24 /dev/usb/2.2.8
crw-rw---- 1 cups hplip 0, 131 28 oct 03:24 /dev/usb/2.2.9
$ id
uid=1001(patrick) gid=1001(patrick)
groups=1001(patrick),0(wheel),5(operator),999(hplip)
Works fine here. There is (was?) a small bug with the hp tools and
cups. Hp-systray does not work if the locale is set to something else
than "C".
