Why don't you try posting your question in the Digital Camera Forum?
I move photos from my PC to my Jornada 720 using a CF card and it works fine but have never done it from my camera to my Jornada because my camera doesn't use a CF card.
I have a gateway DC-t50 digital camera and I was wondering if it were possible to use a female-female usb cable to directly load my pics to my tmobile MDA. If not, is there any other way to load the photos from my digital camera directly on to my MDA. I've tried using the mini-sd card with the sd card adapter in the digital camera and then just load the pics from that card to my MDA, but the digital camera tells me that "the card is not a valid card"
