How to resolve iPhone USB tethering issue with PC's ARM processor?
iPhone Cannot Establish a USB Tethering Connection with PC
Issue Description
USB tethering between iPhone and PC is not working.
When connecting the iPhone to the PC via USB-C or USB-A, the PC recognizes the device, but the internet sharing function does not work. “Ethernet” does not appear in the "Network & Internet" settings.
Troubleshooting Steps
Taken With support from both Microsoft and Apple, I tried the following:
- Updated OS and drivers
- Reset the PC to factory settings
- Sent the PC to Microsoft for repair
- Reset network settings on the iPhone
- Tested on multiple devices
Base unit: iPhone 14 Pro (x2), iPhone 14
Expansion units: Surface Laptop 7 (target PC), ASUS PC with Intel CPU, Surface Laptop 4
USB tethering works on non-target PC, target PC shows " Ethernet" was displayed.
All iPhones were recognized by iTunes on the target PC, but did not show “Ethernet”.
- Tried various cables and USB ports.
Used the official Apple Lightning - USB-C cable.
Tried the same situation on other PCs, no problem.
Final response from Apple and Microsoft
Microsoft
"It works on Intel-based machines, so it may be a compatibility issue with ARM processors. There is nothing more we can do. Please contact Apple."
Apple
"The same iPhone and cable will work on other PCs, so there is nothing more we can do. Please contact Microsoft."
Now I am stuck in a loop between Apple and Microsoft.
I am looking for other steps I can try and possible causes I may have missed.
