initialization. This helps some libraries that setups hardware

Removed DUE and added MKR1000

It’s no longer needed with the timeout mechanism in USBCore.

Timeout is checked on the next send attempt. Initial timeout is set to
70ms, after a time out occurs and the previous transfer is still not
complete a send will report as failed. If a send times out, a ZLP will
be in the send queue to check for future timeouts.
