Re: So easy to fix...
"This device has no reason what so ever to be transmitting on the CAN bus and the transceiver should be configured so that it is impossible for it to do so:"
I can see a market for the "old school" hidden lockout switches. You know, the ones that prevent the engine from running till you flip the obscure switch?
This is the same, but disables the USB port on the dash (or whereever it is) except if you're taking it to the mechanics or such (and they'd probably have access to other ports anyway).
