** [tickets:#318] adapter driver presto - not work**

I'm trying a first time to use Asix PRESTO with OpenOCD. (this Presto is
normally working with the Asix UP software for Windows)
I tried to use in Windows precompiled OpenOCD 0.11 and in Linux fresh compiled
by me.
In the configuration I use "adapter driver presto", or in addition
"presto_serial 013979". However, on both systems, OpenOCD cannot correctly
initialize PRESTO.
