Australian code been hashing since 14-May
cgminer next release will support them automatically (it already does in git)
With current 3.1.1 you need either
--icarus-options 115200:1:1 --icarus-timing shortOR
--icarus-options 115200:1:1 --icarus-timing 3.0=100N.B. the
3.0 will depend on your chips performance but it wont slow anything down (or hash less) if it is wrong, it will just not report the correct MH/s
The
100 ensures it will hash at full speed.
(Edit: forgot to add of course you need
-S device for 3.1.1 for each device also e.g.
-S COM1 or
-S /dev/ttyUSB0)
And to repeat: next release of cgminer will find them automatically (and also allow hotplug of them)
Also note that temperature is important with these devices.
Mine doesn't have a heat sink and gets between 1% and 1.5% errors with ambient low 20'sC
If you are noticing even 1% errors, cooling it down will almost certainly reduce that.
