If you want to plug in a USB device such as a GPS puck, the S2 must be in USB host mode. The ESPTinyUSB library includes a few USB host examples. The acm directory is for USB CDC ACM but I have no idea if this will work for your device.
I have the Adafruit ESP32-S2 TFT board, and I am trying to read in a USB peripheral on my ESP board. I thought this was going to be an easy task and I am quite overwhelmed. I was hoping I could stay in the circuitpython ecosystem, but it seems like making the ESP32 a USBhost is not supported yet. My next level of comfort would be in the arduino ecosystem using https://github.com/adafruit/Adafruit_TinyUSB_Arduino. I believe this will do what I want, but I am having difficulty porting it into the Arduino core. Has anybody here done this successfully? I'm specifically stuck on #2:
