Apple iPhone 15 Pro Max: USB 2 Connection/Speed, no USB 3.1, why?
It appears there is some sort of bug with USB 3 on the iPhone 15 Pro Max.
One very annoying problem with the Apple Silicone Case for the iPhone 15 Pro Max is that the case must be removed for any high quality USB-C cable to be inserted. Doh!
These cables all ought to allow an iPhone 15 Pro Max to connect with USB 3 speeds.
