[sane-devel] Problem with HP ScanJet 4p and SCSI

[David Brant]

Hi Dieter

No need to apologise, your English is perfectly clear to me. The problem
is me and my limited understanding of linux!

Here is my log.

david at david-desktop:/etc/udev/rules.d$ dir
55-scanner.rules  70-persistent-cd.rules  70-persistent-net.rules
README
david at david-desktop:/etc/udev/rules.d$ sudo chown root.root 
[sudo] password for david: 
david at david-desktop:/etc/udev/rules.d$ sudo chmod 0644 55-scanner.rules
david at david-desktop:/etc/udev/rules.d$ ls -l /etc/udev/rules.d
total 16
-rw-r--r-- 1 root root 1362 2009-06-07 13:06 55-scanner.rules
-rw-r--r-- 1 root root  459 2009-05-28 21:51 70-persistent-cd.rules
-rw-r--r-- 1 root root  392 2009-05-28 20:19 70-persistent-net.rules
-rw-r--r-- 1 root root 1398 2009-04-09 01:19 README
david at david-desktop:/etc/udev/rules.d$ 

After re-boot i get:

david at david-desktop:~$ ls -l /dev/sg2
crw-rw---- 1 root users 21, 2 2009-06-10 20:01 /dev/sg2
david at david-desktop:~$ 

In addition:

david at david-desktop:~$ cd
david at david-desktop:~$ touch dummy
david at david-desktop:~$ ls -l dummy > out
david at david-desktop:~$ rm dummy
david at david-desktop:~$ 

with contents of out being:

-rw-r--r-- 1 david david 0 2009-06-10 20:11 dummy

Please let me know if i made a mistake! :-)

Regards

Dave
