[SOLVED]Cannot move files from mounted usb drive

Question

When I try to move a file off of my usb drive I get the following error:
mv: cannot remove ‘homework-1.txt’: Permission denied
The usb drive is mounted to a folder that I created as a normal user in my home directory. However, when I call ls -l on my home directory it says that the directory I'm using as a mount point is owned by root:
$ ls -l | grep mnt/
drwxr-xr-x 10 root root 4096 Dec 31 1969 mnt
When I unmount the flash drive, the ownership of the mount point changes back to me:
$ ls -l | grep mnt/
drwxr-xr-x 2 hugo hugo 4096 Feb 4 16:12 mnt
When I move the file I want as a super user it works but I don't get to retain ownership of the file anymore.
How can I make it so that when I mount the usb drive I have access to it as a normal user?

Seems to me that udev is giving ownership of the device to root and no write permission to world. Try adding something like:
SUBSYSTEM=="block" ID_BUS=="usb" GROUP="users" MODE=0660
to /etc/udev/rules.d/10-locale.rules
Read up on http://www.reactivated.net/writing_udev_rules.html
no, just no.
To expand on this... the rule changes permissions on all USB block devices (and will change permissions on some sysfs nodes as well), which is dangerous and doesn't accomplish what the OP wants -- to change permissions on the filesystem. You've also given the rule an irrelevant name (locale? wat?), and then point to an incredibly outdated resource (last updated nearly 6 years ago!!!) about udev rules. udev(7) is far more relevant and up to date. It doesn't mention outdated commands which no longer exist (udev$foo were all merged into udevadm).
