usb device root permissions write access

lindylex · 06-04-2007, 01:35 PM

Is there a way to change the permissions of my usb devices in Linux? Currently all my usb device(s) I cannot write to, only the root user. I want to write to my digital camera’s drive connected to my computer.

I can not use /etc/fstab because the devices are loaded dynamically.

Thanks for your help.

Hya,

How do you mount your usb device? pmount? Do you use udev?

Hya,

How do you mount? If device is mounted by root using pmount (or mount), non-root may not have access to it. Use pmount as non-root.

Debian linux will load the devices dynamically. There is a solution that enables the permissions so anyone can write and read to the external devices that have dynamic mount points. I ran into this problem on Fedora Core.

I will look into udev and pmount a little more. Utanja can you tell me more about udev? And how you resolved this problem?

Kaz2100 can you tell me how you used pmount to solve this problem?

You have to edit some rules under /etc/udev , then do a "/etc/init.d/udev restart"

As non-root user,

Code:

pmount /dev/*** Name

I use Debian Etch, and it works without editing udev files. XFce also handles similar way.
