Accessory not supported. USB-C to Lightning Adapter

Hi.

I've been using lightning to USB 3 camera adapter to connect with audio interface, Focusrite Scarlett 2i2 (3rd Generation).

I've purchased iphone 15 pro max recently, so I purchased USB-C to lightning adapter - to connect with the iphone 15 pro max charging port.

Iphone pro max indicated that "Accessory not supported" and it didn't power up the audio interface device (i.e. Focusrite Scarlett 2i2 3rd generation).

I checked with focusrite control apps, no firmware updates is required for my audio interface device.

Appreciate some help and assistance. Thanks.
