That's my point. If I can't tell whether this charging cable is secretly an USB keyboard, isn't it better to explicitly tell my cellphone to treat it as charge-only instead of relying on physical solutions?
- zdkl 6y agoMy use case is I don't necessarily trust one end of the connection to behave, so I want the ability to just give/take power and involve exactly 0 software. I understand that's not the usual consumer story, and the best argument I can come up with for the general case is it could make any USB compatible wall plug safe to use to charge up.
- mFixman 6y agoI'm talking about using the phone's software to block the data connection. If you don't trust that cellphone won't transfer your private data via USB, I don't understand why you trust it not to do it via any wireless connection.
