TouchOSC and Teensy 4.1

Hello everyone,
I am using touchOSC installed on an iPhone 16 Pro Max.
I created a template that works to control my Synth on Teensy 4.1 using the Audio library.
When I connect my Akai controller to USB Host using the USBHost_t36.h library it works fine.
When I connect my iPhone to my MacBook, I receive the MIDI stream from TouchOSC.
But when I connect a USB C cable (iPhone side) and USB to the USB host port of the Teensy, I receive nothing.
Does anyone have any idea about this problem?
 
I think you're connecting a Host (iPhone) to a Host (USB host port) which doesn't work - can you connect the phone to the usb device port on the teensy.
 
Yes, I suspected that this was the cause, but when I connect the iPhone to the MacBook, I also have two hosts.
 
on the teensy the usb host port is only host (your iPhone and Mac can switch between host and device duties)
can you connect the teensy as a device using the other port?
 
Check <this> thread for a similar discussion that might be what you are looking for (can't be sure that I understand your question correctly).
