It sounds like the LXDE desktop isn't properly handling permissions; I'm guessing this is the same bug as the Shutdown operation not working, and WiFi configuration not working.
I'm more of a server-side expert myself, and don't know why this is happening.. There's a lot of moving parts involved - dbus, systemd, consolekit, lxdm, udev.. I'll see if I can figure it out soon, but it might be faster if someone who understands the parts has a go.
In the meantime, do note that all these operations work fine if you do them via "sudo" and traditional methods.
eg. "sudo mount /dev/sda /mnt" to mount a usb storage, or "sudo vi /etc/network/interfaces" to set wifi configuration. (using wpa-essid and wpa-psk options)
