Maybe this is a dumb question, but is it possible to use the Teensy 4.1 USB host hardware to communicate directly with a PC? I essentially want the USB host on the teensy to send raw data back and forth between my PC in a way that looks something like this: https://www.pjrc.com/teensy/rawhid.html

I guess I'm confused about whether two hosts can communicate with each other -- is there a way to set my teensy host to be a USB device instead?
 
Indeed two USB Hosts won't communicate. And So far the T_4.x USB Host hardware has only been supported in HOST mode.

This can work using a UART to USB adapter from one of the T_4.1's serial ports. Even a second Teensy's USB Device port could be used where it has a UART Serial connect to the T_4.1 and echoes incoming data out the USB port.
