Thanks for a great forum!
I am having this strange problem when trying to connect my iPhone Xr to my new JDS OL DAC through the Camera connection kit and a Forza USB cable.
My iPhone charges as normal and I can connect to my headphones via the lightning - minijack dongle. But it is as if it does not register the connection with the dac. I have tried with two different USB cables so I am assuming that the iPhone is the problem.
My son’s iPhone SE and my girlfriend’s iPhone 7 both connect without any problems.
