Weridly specific issue with usb port and iPhone

Framework Laptop 16 Linux
1

Arch Linux using kernel 6.12.27-1-lts

For some reason the left back port on my framework (port 1 according to the website) refuses to connect correctly to my iPhone using a usb-c to lightning cable, it keeps continually connecting and disconnecting, I’m using libimobiledevice to connect arch with ios. This happens regardless of the expansion cards the issue only happens when plugged into that specific port, every other port works fine which is weird, there’s also not an issue with the ‘faulty’ port when I charge through it or use my usb dock connected to it. It’s just this specific port with this specific phone.

Connecting and disconnecting the phone using the faulty port:

“Doctor, it hurts when I do this!” “Then don’t do that!” :wink:

Seriously though, have you tried this? It solves a huge range of minor hardware problems.

Does it have an issue if connected with a usb-a to lightning cable?

Might be the same issue that some have reported here community.frame.work/t/usb-c-is-not-compatible-with-iphone-15-pro-pro-max/38349/

Note that it’s not happening to everyone’s Framework and their iphone: USB C is not compatible with iPhone 15 / Pro / Pro Max - #59 by GhostLegion, which makes me suspect that the issue is not so straightforward. And that the cause might be a combination of issues with both the iphone and laptop. So the phone works elsewhere, and the laptop works fine with other phones, only in together does the problem appear.

Here someone seemed to report that their iPhone 15 was working fine before it was updated to IOS 17.1.2. USB C is not compatible with iPhone 15 / Pro / Pro Max - #129 by JenJ. Which would point to an apple firmware / software bug being the cause. At least in their case.
