No matter how I chmod the files on the mounted share I could not get the permissions to stick. I came accross a solution online and figured I would post it here.
The solution was to mount the USB drive with the following command line.
mount /dev/sda1 /mnt/usbdata -o users,umask=000
This allowed all of my users access to the device. Normally I would not want this but in this case I just have the space for extra backups and scratch space.
Hope this helps someone else.
