If you want to do this at the $1 price point, you can on RP2350, albeit with some limitations. In particular, it maxes out at full speed (12Mbps). The trick is to use the on-chip USB peripheral for one, and connect the other to GPIO pins backed by PIO.
This works today with tinyusb and pico-pio-usb, but I'm also playing with a Rust port which I'm hoping will have higher performance.

- raphlinus 2mo agoEntirely fair, $1 is just the chip, not the board. No question the ESP32-S3 is incredibly good value.
