Official Adapters getting Accessory not supported message?

[SystemDweller]

Hi!

When I connect two official adapters together and plug into my MacBook Pro M3 Pro I get an 'Accessory not supported...' message.

Does anyone know why they are incompatible?

USB-C to Lightning Adapter and Lightning to USB-A Adapter


Thanks!

Yes I am aware of that mate. I was just trying a workaround to save buying a USB-C to USB-A cable and wondered why both wouldn't work together.

Thanks for your reply!

This. And same with the other connector.

Since there are chips within the connectors, there is a verification process going on that probably does not go through the full chain of connectors. No pass-through from one MFi connector through/to another. The "outermost" cable is probably not getting verified as legit.

The Made for iPhone and iPad (MFi) licensing program provides vetted accessory manufacturers access to the iPod Accessories Protocol (iAP).

As proof of authorization, the accessory sends an Apple-provided certificate to the device, which the device then verifies. The device then sends a challenge, which the accessory must answer with a signed response.

Ah that makes sense. Thanks for your informative reply.

I wonder if USB-C iPhones/iPads have a USB-C Lightning Alt Mode like USB-C Thunderbolt Alt Mode or USB-C DisplayPort Alt Mode or USB-C HDMI Alt Mode?
Search for "Alternate Mode" at https://en.wikipedia.org/wiki/USB-C

Buy the cable.
They're not expensive.
