Cf Usb Adapter What Kind Of Adapter Do I Need For Express Card?

What kind of adapter do I need for express card? - cf usb adapter

I have a sound card uses an ExpressCard slot. I need an adapter for it. I want to be the name of a product or a product used on the Compact Flash slot as in the Express Card slot. Who knows what I'm talking about or what I need? I tried a USB, but not, I do not think enough "juice" to keep the card itself and power. I will try another USB very soon wanted to, but know of one for the CF slot. In the search for one of them was so confused! Thanks in advance!
