USB to CF How to make that?

Hello, I wonder.
Does anyone here know how to link a USB to a CF card?
Since well USB only has 4 Pin-Outs and CF has 50...
Compact Flash pinout


I know there are devices that can do that. But well I need to know how that works.
Since I am working on a PDA. And I cant make a Circuit but I can do wires
heh, Well does anyone know how to do that with Wires?
And, what is really important is I should be able to run a GPS CF card and a GPRS CF card.

Well let me know how this all works..

Thanks.

Cheers,
Robin

 

So you want to run a USB input to a CF input to PDA?

USB ----> CF ----> PDA

Is that correct?

 

The other way around

Its a Custom Build PDA that has a USB Board.
So I want to do it like this:

PDA -> (+Extra Battery) USB -> CF


Any ideas?
