Seems doubtful that they have more than one that works without even taking apart the phone. This one is really bad and Apple should be able to figure it out without seeing it...

That would be interesting, and it would also be something not called USB.
-
Sure it's USB (or rather USB over lightning). It's just 2+ separate logical USB devices, and which is connected is gated by lock state of the phone.

This starts to become a highly specialized phone that is useless when locked. Might as well turn off bluetooth, wifi, and push notifications while locked. How is this isolated set of chips going to know when the phone is unlocked? Who is going to signal it?
-
Software can switch it all when entering locked state. I've actually never used my phone's USB port for anything but charging & initial OS install so it hardly seems "useless" to me.
-
You’re mixed up. You’d introduce a hardware isolation gate to protect the OS from port access while phone is locked, but the signal controlling the gate (“user unlocks phone with PIN”) has to come from the OS side of the boundary. How does that help?

Not going to continue responding with your condescension.

I’m sorry - I didn’t mean to be condescending.

Apology accepted. Idea above is that you can (modulo very different classes of attack) assume the OS is uncompressed as long as the interface surface to it is mostly or entirely cut off.
