Hi All
I need to test a usb printer from my user space test code. The test
code
could do it well when i am a 'root user' but fails when i login as a
'normal
user' .
Isn't it obvious?
If you want a normal user to manipulate the device then try adding the
udev rules or manually do a chmod and try.
[ snip ]
Why do you want this?
Thanks for your response.
With chmod, it works but its a temporary solution. if i restart or
re-connect the device , the permissions are again the default one.
I dont have /udev or /sys in my system. Is udev available in
2.4.21-37.ELkernel. Do i need to re-install or pl let me know if any
other option.
I need this bcoz i want to read usb device's configuration from the
testfile and need to open the file in /proc/bus/usb/XXX/YYY as normal user
and not as an root user.
Only read permissions are available for the file /proc/bus/usb/XXX/YYY
to the normal user and i want to have rw permissions.
thanks
ravi
regards,
Girish
