When I connect the iPhone to the USB-C terminal of my laptop, I don't find my iPhone in my files. Found the cause of the error: cmd 'dmesg'

[ 7795.969752] usb 1-1: new high-speed USB device number 6 using xhci_hcd
[ 7796.123675] usb 1-1: New USB device found, idVendor=05ac, idProduct=12a8, bcdDevice=12.08

[ 7796.279873] apple-mfi-fastcharge 1-1: USB disconnect, device number 6

I feel that this is caused coz of the Apple-MFi driver, but not sure how to disable it.
Could someone help me in getting this fixed as I have very minimal knowledge in Linux drivers.

This happens only on my Ubuntu, while other users were able to connect to my iPhone as it always have been. The only difference I could see was apple-mfi-fastcharge 1-1: USB disconnect, device number 6 was missing.

INFO: I am using the latest Ubuntu 20.04.5 LTS OS. iPhone SE 2020 running iOS 16.0.3.

Please edit the question and add the info there not as a comment. As for the driver there does not appear to be one. It is using the USB driver the rest is in the phone. Maybe try an Apple site and see if anyone has some idea.

I don't think connecting with Apple community would really help, as I was able to connect my iPhone to other users' machine running UBUNTU.

The exact same version with the same updates and the same soft wares installed?

Yes. It was the exact version of Linux and iOS.

I also tried enabling Fast Change support for Apple devices from the [link](https://unix.stackexchange.com/questions/592775/how-can-i-enable-apple-ios-fast-charge-support). But was not able to find `99-iphone-fastcharge.rules` in ```/etc/udev/rules.d/99-iphone-fastcharge.rules```

I updated to latest Ubuntu 22.04.1 LTS, but the issues still persists.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
