If the usb is in ntfs, you have to install fuse first, then install ntfs-3g tools. Use fuse 2.6. fuse 2.8 is not working properly.
After installing fuse, type the following command to test the fuse.
#modprobe fuse
if you didn't get any error message means, fuse is installed the module is loaded properly.
Now you can install ntfs-3g tools. Without fuse, ntfs-3g tools are useless.
