Thanks for the help guys! |
Doing **anything** on a DX is risky, since if it bricks, it will be very hard to un-brick.
Anything that you can do, your kid can undo, but ...
With those cautions out of the way:
Disabling the button function might require modifying the firmware.
Easier, change the firewall rules.
The "stock" rules accept all packets out-bound from the device;
Change that part of the iptables rules to drop all packets out-bound from the device
EXCEPT those using the USBnetwork interface.
You need to leave a "path" in/out of the machine so that you can clear/set your desired changes.
But see my second note above - your daughter will find it, someday.
You can "harden" that path by limiting the USBnetwork to ssh port **only** and then configuring the dropbear ssh server on the Kindle to do pub-key authentication **only** -
And then keep good, physical control of your copy of the matching key-pair key.
I can't give specific directions, I don't have a DX model myself.
