Rootless X is owned by xuser, the problem is xuser doesn't have permissions to
write usb storage when the type of filesystem is vfat.
...
$ mount
/dev/sdb1 on /media/sdb1 type vfat
...
$ ls /media/ -al
drwxr-xr-x 2 root root 16384 Jan 1 1970 sdb1
...
The usb storage is mounted to `/media/sd**' by a udev's mount.sh script,
modify the script to invoke pmount by xuser to resolve this issue.
