What's working?

1. "test" on pk2-2550-48.fm + just PK2 connected, after 2nd try after full unplug.
2. ctrl-C + reload .live + "test"
3. ...
4. ...

5. "testi", all the same
6. ctrl-C + reload .live "testi"
7. ...

NOT WORKING: The same, but using serial console.  Disconnecting the
power might help.  Nope... something weird is going on.  Maybe some
ports are disabled or something?

Let's cut the power from USB-TTL, see what happens then.

Trouble was that "PIR2 USBIF low" was needed.
