This gets USB CDC printing working..

add some more missing files now that it includes the symbols..

convert to using stdio to line buffer usb output... This reduces
usb traffic like when doing hexdump...

The delay works, but could be a problem on slower systems...  It's
been reported, so hopefully a fix will happen..

python2 is incompatible w/ python3 code, and assuming that python
is 3 is bad, so use python3 which ensures that the correct version
will be run...

and should only be used w/ Python 2 scripts.

The first one is just more defensive programming, not sure if I'd seen
this failure..

The middle one did fix some hangs...

Last one is to ensure that the schedule processes more quickly and
not enforce each command to take one ms...

This is better, as if anyone allocated memory before, we will not use
that memory, and still use uninitalized memory..
