268bf6f99e atmel-samd: Fix non-DEBUG USB cdc. 
I believe the issue was that LTO exacerbates a problem where a CDC
read is initiated but fails and leaves pending_read true
preventing further reads.

4aeef100f6 atmel-samd: More USB polish 
* Introduce a python script to generate the USB descriptor instead of
  a bunch of C macros. In the future, we can use this dynamically in
  CircuitPython.
* Add support for detecting read-only mass storage mounts.

Fixes #377
