Thank NONAKA Kirihimo and Peter Postma :)

I have run my SL-C3100 from the CF flash card exclusively so that is 
should work fine.

No idea.

Not sure, I only use usb for devices on my zaurus.

I use my usb port with a powered hub for wifi, bluetooth, gps so 
essientially it's a regular usb port although non-powered.
