Send a USB descriptor string. The string is stored in PROGMEM as a plain ASCII string but is sent out as UTF-16 with the correct 2-byte prefix

Watchdog functions. These are only safe with interrupts turned off.

Number of bytes, assumes a rx endpoint

Non Blocking receive Return number of bytes read

Sanity: ensure parameters are within area bounded by store

behind the scenes function that is called when data is received

Access the raw byte array containing the address. Because this returns a pointer to the internal structure rather than a copy of the address this fun

Forcing this inline keeps the callers from having to push their own stuff on the stack. It is a good performance win and only takes 1 more byte per us
