Teensy 4.1 USB Host

[rayhall]

Hello Everyone,

I have a Teensy 4.1 board that i am inserting into a motherboard PCB that already has a USB socket that can be accessed outside the project enclosure. I have designed the motherboard pcb
to connect to the USB Host pins on the Teensy 4.1. Can I program this way and use it as a serial USB port ?

I do not want to have to open the enclosure to do the programing.

Ray.

No, sorry, loading code is only supported on the USB device port.

Thank you. I was afraid of that

I install pogo pins underneath the USB device test points to access the device end on a carrier board. I believe there should be a drawing somewhere that dimensions their location and mapping on the board.
