Unable to mount external USB devices

[MdeVicente]

When trying to mount an external USB device with my recently updated Ubuntu 12.10, an error message appears saying:

Adding read ACL for uid 1001 to `/media/user' failed: Operation not supported

I never had such a problem with previous versions. Please, I would need help.

Maybe a permissions issue? My permissions on /media are 755 owner and group are root.
On the sub folders the permissions vary - you could change the "user" folder to 777 to make the permissions wide open. Also make sure that /media/user is a folder and not a file

Looking for permissions I realized that the folder "user" didn't even exist. It seems that Ubuntu 12.10 doesn't mount the devices in the folder media directly, but in a subfolder with the name of the user. I created it and settled the permissions to 777, and my problem is already solved.

Thank you very much.

I have this same issue. (Never had it on previous versions of Ubuntu, but with 12.10 all external USB Thumb Drives I insert into the USB slot give the same message.)

How did you solve this?

To mount external devices you must have a folder with the name of your user in the folder media. As an administrator, you type in the console:

cd /media

to go to the media folder. Then:

sudo mkdir user

where user is the user name, to create the folder. The new folder belongs to the administrator. To make owner to your user:

sudo chown user user

Another choice is giving permission to everyone to write and read in that folder:

sudo chmod 777 user

After that I had no problem to mount external devices.
