Teensy 4.2, now with USB-C?

The thread title line pretty much sums it up. No changes to the board or chipset as it’s already great! Just swap the micro port for a type C (even if it’s still just using it at 2.0 speeds). Obviously include the pulldown resistors in case people power it with a “smart” brick.
 
The problem with including pulldown resistors is that it locks the port into acting as a device. The existing micro usb port is possible to use as either a device or host port.

Do you mean in theory? I was unaware that female micro-USB plugs could act as a host, let alone the Teensy port acting like a host. Would you mind clarifying?
 
The USB connector on Teensy 4.0 and 4.1 is Micro-B. Using USB spec conforming cables, it's only usable in device mode. Or course with a non-conforming cable, anything goes...

Teensy 3.2 had a Micro-AB connector, which could mate either a Micro-B cable or Micro-A cable. But Micro-A and USB OTG never really took off.
 
I wouldn't call them "non-conforming" cables... plenty of mobile devices with micro usb were certified for OTG.
 
I will also throw in my vote for using a USB-C connector. Virtually everyone is doing it these days and who doesn't want to be like the cool kids. USB-C has the advantage of being a lot easier to socket. I think everyone needs three tries to properly insert microB adapters.
