Cant do "mount/umount" on USB flash drive as regular user

This is my problem: can't mount USB flash drive as regular user.
When I try to mount error msg appears:
Could not mount device
The reported error was:
mount: only root can mount /dev/sda1 on /mnt/usb
When I execute:
ls -l /dev/sda1
brwxrwxrwx  1 root disk 8, 1 1995-04-29 12:33 /dev/sda1
because I have already set '777' on /dev/sd1.

This is my fstab:
/dev/hda3        swap             swap        defaults         0   0
/dev/hda9        /                ext3        defaults         1   1
/dev/hda10       /home            ext3        defaults         1   2
/dev/hda8        /tmp             ext3        defaults         1   2
/dev/hda6        /usr             ext3        defaults         1   2
/dev/hda7        /var             ext3        defaults         1   2

/dev/cdrom       /mnt/cdrom       auto        noauto,owner,users,rw  0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
/dev/sda1        /mnt/usb        vfat  
pamconsole,exec,noauto,owner,users,noatime,codepage=850,iocharset=iso8859-15,managed 0 0
My user belongs both to 'root' and 'users' group.

Does anybody knows where is the problem?

As a follow up, you might consider using a udev device instead of /dev/sda1 to mount your drive. If you have things set up properly (a topic about which google can point you to adequate information) then you can always mount a particular device on a particular mount point.

For example, when you plug in your digital camera and it comes up as /dev/sda1 also, you don't end up mounting it on /media/thumbdrive. udev can give it a different node name based on lots of parameters, manufacturer or serial number for example. You could have udev create a node /dev/camera for the camera, /dev/thumbdrive for the thumbdrive, and then in fstab you would reference /dev/camera and /dev/thumbdrive instead of /dev/sda1.

I've found that convenient anyway...
