home made os on ipaq (Platform Builder)

hi,
I want to make my own os (Windows CE) for ipaq (1930). I have compiled it with Platform Builder for the right processor Samsung 2410. I now want to download it on the device. I have a few questions
:
how do I transfer the new image via the usb cable, while the Platform Builder proposes me only serial or ethernet?
can I save the actual os (the default one) ?
thanks
Pierre
