complain about them being undefined.

This avoids sending data to the host while the tty is in echo mode,
which only generates sadness.

  chips/samd21: Make sure in_wait is called before in_send

ao_usb_flush was calling in_send without making sure that in_wait
had been called first; this could cause a pending packet to get
smashed if the new packet was empty

  chips/samd21: Use dfll48m for USB even when we have xosc

For unknown reasons, running USB off the dpll96m generates garbage on
the USB bus, ending up dropping packets or getting us kicked off
entirely. Give up trying to make that work and just light up the
dfll48m so that USB is reliable.

  Use 'official' USB ids for Adafruit products

These are the IDs reported when running the Arduino stuff, so at least that
doesn't conflict with circuit python or the UF2 boot loader.
