Stache for me with USB BoE

Hello!
I bought this Stache from Emesystems. So far so good! To download a program from my computer, the Quick Start tells me to use my normal programming cable, as I understand with DB9 connectors in both ends.
Well, my Basic Stamp Board of Education is the USB version, so I use a USB cable there.
So I guess I need to make my own cable for the Stache.
Now I need to know how this cable is, what pins are used, is is stright through meaning the pins on the computer side are the same pins on the Stache side?
And finally, how do I make the computer find the Stache (on the COM port), I guess its probably not as easy as with the USB Stamp, do I need some kinds of drivers?
MY problems are related to downloading programs to the Stache only, not when uploading to the Stamp as I will use DB9F connectors on my projects. Quick Start gives a good description on that.

If you have a dedicated 9 pin DB9M serial port connector on your computer, you can plug the Stache right into that, using the DB9F to DB9F adapter. that comes with the Stache. Or, you can plug a straight thru cable into the computer, and plug the Stache with its adapter into the other end of that. (It is a "modem" cable, yes, with the numbers connected 1-1, 2-2,...9-9).
If your computer does not have a dedicated serial port, you can use the FTDI USB to Serial adapter that Parallax sells, and the Stache can plug right into that with its adapter. You already have the drivers you need, because you can already program the BOE-USB
In either case, the IDE will search through all available serial ports, both hardwired and USB-virtual, until it finds one with the Stache attached. Just like with your BOE-USB.
To deliver programs to the field, the Stache only programs Stamps that have a standard RS232 programming port, not the USB version. I.e., the Stache can't field program a BOE-USB.

Thank you for quick reply, now I see if I can find a cable or just make one. Connecting right into the serial port will be too difficult each time as the port is located on the rear side of the PC, the whole box have to be moved and other accidents could happend!
The Stache won't be used to deliver programs to the BOE, the BOE is only located in the prototyping-area, close to the computer. I always make another board for the projects after being developed and tested on the BOE. And here I guess the Stache will be useful, as I no more need to remove the Stamp from the board each time I need to re-program.
