Observed instability in controlling devices when OUTPUT_ENABLE wasn't
enabled in the first step. I couldn't find any documented reason why
this is, but the documentation does say: "FtdiOutput Pin always kept at
1".
Alpaca always keeps OUTUT_ENABLE as 1, and never turns it off. The
documentation seems to imply it should always be left on. This change
updates the open sequence so that the OUTPUT_ENABLE bit is set first.
