Wireless Scan with Kodak 5250

[maxass]

Thanks for the quick answer, Joe.
The WIA service is running already, otherwise a USB-scan wouldn't possible, would it?
Do you have an idea how to add that wireless scanner manually to Windows 7? If I choose "Add device" from the "Printer & devices" (sorry, not working with an english os so names are tricky) I get a typical control panel window saying "Choose the device you want to add." and underneath that "Looking for devices...make sure the device can be found." There is nothing I can do, nothing to click...
