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.

I wonder if Apple's applications for Windows – iTunes for Windows, Apple Devices – are Intel-only, and depend on Intel-only drivers. Like macOS for Apple Silicon, Windows for ARM can run some Intel-only applications, but can't run Intel-only system code.


Microsoft Support – Windows Arm-based PCs FAQ


"Drivers for hardware, games, and apps only work if they're designed for a Windows 11 Arm-based PC. For more info, check with the hardware manufacturer or the organization that developed the driver. Drivers are software programs that communicate with hardware devices—they're commonly used for antivirus and antimalware software, printing or PDF software, assistive technologies, CD and DVD utilities, and virtualization software.


If a driver doesn't work, the app or hardware that relies on it doesn't work either (at least not fully). Peripherals and devices only work if the drivers they depend on are built into Windows 11, or if the hardware developer has released Arm64 drivers for the device."


That would explain Microsoft pointing the finger at Apple, and IF this is the cause, only Apple could fix it (by putting out Windows/ARM versions of their code).


You could raise the possibility with Apple, and ask them if this is the issue – although I'm not sure whether the first-level Support people would understand what you were asking unless you explained it very clearly. (Even then, they might need to check with other people in Apple in order to give you a clear answer.)

As a basic Tech consumer user when I purchased the new devices, I didn't even know anything about Arm.

Talk about security issues, then here's one then for Apple and you.
Today I received a Meta email notification on the new Iphone 16 Pro.
I don't use LameBook, the account was set up for me back in 2022 for a particular professional affiliation because apparently a human doesn't legitimately exist today if they don't retain these sorts of digital accounts (at least that what I was advised at the time).

Well today I receive an email with the message that some contact has "shared a link". Usually, I just delete all those email notifications. But as I've been setting up the new Iphone 16 Pro manually entering in ALL my contact details when the email came through I decided to click on the link, thinking that it may lead me to an interesting article or information online. Low and behold, what do you know? Unimpressed Look.

The new Iphone automatically logged me into this personal LameBook via safari without ever even prompting me for my email and password. How has that occurred?
Now I've never even used LameBook on either of the new devices and I've also, never ever had an FB/Meta App either on any of my previous devices before.
I certainly have not consented to my email or password being stored anywhere in web browsers or Apps.
The half dozen odd times where I had to login and add information to the FB profile was completed online via a web browser.
I don't like anything to be automatically logged in, and I always clean out web browser content after each use.
I'm not even logged into my Apple account on the new Iphone 16 Pro.

So, how exactly has safari via the new Iphone 16 Pro managed to log me into the Meta account automatically and also then show everyone else in the world that I'm supposedly also online?

If that is not bad enough.
Additionally, ALL my location settings on the new Iphone are set to OFF, same with the Find Me App and options.
However, after this automatic login occurred, Meta then sent 2 follow up emails stating someone just logged into my account in the Sydney location. CREEPY MUCH.

Nothing is secure when it is online.
To me, Biometrics are like DNA, they belong to the individual. My personal information and ownership of it belongs to me.
What BIG TECH and governments habitually fail to accept is that for some individuals, surrendering one's personal biometrics is almost as invasive as having to undergo an autopsy!
Other's can freely disagree with my sentiments, but I don't want other unknown people ferreting around my stomach contents once I'm gone, and that's precisely how I think and feel about my biometrics. While I'm still very much alive then no one else genuinely legitimately requires access to that personal intimate information and physiological data.

Use of iCloud Keychain or the usual migration from old to new iPhone would have passwords and passkeys available to Meta and other services, and the usual migration would migrate the apps as well, but I’m unclear about the need or expectations for that Meta account given your earlier “I don't need nor do I want mobile social media”.


And for assistance with Meta privacy settings, access, or security check with Meta Support. Or delete your Meta account entirely of course, if you want to greatly reduce your use of that social media service, per your earlier comment.


For your feedback on biometrics and such, best discuss that with your legislative representatives.

About Face ID advanced technology - Apple Support


"Face ID data — including mathematical representations of your face — is encrypted and protected with a key available only to the Secure Enclave."


"Face ID data doesn’t leave your device and is never backed up to iCloud or anywhere else."


"Within supported apps, you can enable Face ID for authentication. Apps are notified only as to whether the authentication is successful. Apps can’t access Face ID data associated with the enrolled face."


Indicating that your biometric data is not going into online databases belonging to "BIG TECH and governments". There are similar protections for fingerprint data when using Touch ID on an older iPhone that uses that, instead.

True.


To me, Biometrics are like DNA, they belong to the individual. My personal information and ownership of it belongs to me.

Which is why Apple only stores it on your personal device, in encrypted form, and it a format that can't be transferred off the device. See the post from Servant of Cats for details.


However, regarding personal information, that horse left the barn 25 years ago or more. In 1999 Scott McNealy, founder and CEO of Sun Microsystems, in a speech at a security conference, said; “You have no privacy, get over it."


Some food for thought:


  • Your carrier knows the location of your phone all the time, even if you turn off location services, because it can triangulate from the towers that receive your phone’s periodic “I’m here” ping. They are required by law to do this to support E911. They upload this information to databases where your location and whereabouts are known to law enforcement and any business that cares to know where you are.
  • License plate scanners are ubiquitous, in police vehicles and repo trucks. And also along limited access highways, toll roads, bridges and tunnels. And every time your plate is scanned it goes into a location database that is accessible to law enforcement and any business that wants it.
  • Electronic toll tags are obviously used every time you use a toll facility, but transponders are located everywhere along highways for traffic control. Have you see signs that display how long it will take to get to an upcoming milepost? Where do you think they get that information?
  • Do you use public Wi-Fi, your cable provider’s hotspots or the “free” convenient Wi-Fi networks in malls and stores? Did you think that your location wasn’t tracked by those?
  • Regarding “private" biometric data, See those cameras in stores, malls and other public places? Have you heard about facial recognition?
  • Did you ever post your picture in Shutterfly?
  • Did you ever use Avast?
  • Do you have a Transit Pass account?
  • Do you use an urban bicycle rental like New York’s CitiBike? Have you noticed that your usage history shows the location and time you picked up the bike and likewise when you dropped it off?
  • Do you use credit cards in stores? Did you know that the location where you use a card is recorded in a worldwide central database, ostensibly to detect card fraud through what’s called a “velocity check” (AKA as the “superman test”)?
  • Have you heard of iBeacon? It’s a feature that tracks and reports the location of any device that has Bluetooth enabled on a device.
  • What about Find My iPhone, which always knows where your phone is? And its feature added in iOS 12 that uses the Bluetooth signals from other phones to anonymously crowdsource the location of a missing phone? Even when the phone is powered off?


Apple is about the only business in the world that does NOT track you.
