you are challenging us...
Unfortunately, the Sandisk Connect Plus is not working at all on a Zaurus with Sharp ROM. But it contains the config files to enable at least the Memory part.
But you might have some luck with the Cacko ROM on which QuantumSTEP should also work.
The second thing is that the actions for the Activate Menu are not correctly working.
So the only recommendation I have at the moment is to wait for the next releases.
