Guess I’m just too dumb to do it the right way. The option for IPv6 Host Exposure does nothing for me. Any advice? I put in my device with the right mac address select the port, open the port on my end (sudo ufw allow 4000) and then I check online and it doesn’t work

Yeah it works with IPv6, but my Vodafone router sucks ass, so I had to disable the firewall of the router all together

For example having 3x the pins is a big plus. I don’t know why you are so focused on not including the protocols a port can use. Apple will most likely use USB to make connections between PCs and their Phones possible. And you have to have connectors capable of carrying the signals for those protocols.

The huge speeds of USB 3.0 (USB 3.2 Gen 1x1) and up are because of added twisted pairs carrying the signals in duplex (Plus a new USB A connector). Anything above USB 3.2 (USB 3.2 Gen 1x2 and USB 3.2 Gen 3 2x2) needs to use USB-C because the older USB-A Connector doesn’t have enough pins to allow a connection to a cable with 4 twisted pairs (plus one for backwards compatibility).

I think the lighting connector is enough to allow for a USB 3.0 connection, but you would have to switch the signals after it comes out of the port somehow, as the 3rd pair is not used during FullSpeed (I think there’s an adapter that does this)

Even if they don’t use USB and develope their own protocol, it’s gonna benefit from more parralel connections

The lighting connector only features two differential pairs. But as I understand it, USB 2.0 can only use one of those. The next upgrade would be USB 3.0 (Officially USB 3.2 Gen 1x1, but let’s not get into that) which uses 2 differential pairs but also keeps the USB 2.0 connections untouched, so it needs 3 pairs.

Maybe you could cheat and get a non compliant USB 3.0 device connected via lighting to USB A, using one of the pairs for setup, then going into SuperSpeed mode and using the two pairs in full duplex (both ways at the same time). Maybe that’s what the Lightning to USB3 Camera Adapter does.

USB-C has the capacity for 4 shielded differential pairs, the 2.0 comparability pair and two pins for alternate mode, which makes it not only capable of, but necessary for USB 3.2 (USB 3.2 Gen 2x2 and USB 3.2 Gen 1x2) and upwards. (Don’t ask me about USB4 (not named USB 4 for some reason))

Lightning has some other quirks like being able to carry UART, JTAG and other Debugging stuff, which is communicated with a chip inside the phone/tablet etc. But since that’s closed source, it’s only been reverse engineered

It’s good if you don’t need speed.
