I got this working with wifi (really cool btw), but it would not work with just USB and ICS. The pc saw my omnia and tried to install drivers. What drivers would I need? I have a netbook so the omnia CD wouldn't work (and I don't have it available anyway).
Make sure ics is installed on device. put device to usb mass storage mode. And connect to computer and yes it will need a couple of usb drivers. On my win7 acer netbook it found drivers through wifi and went fine. Once you can browse device from computer turn off wifi on netbook and run ics on device. settings should be "pc connection : usb" "network connection : broadband access" should be flawless from there. And I don't even have device center or active sync on this machine.
