John,

Is your HP software Adobe Photoshop LE this is the one I am using. Should you need one just drop me an email and your address or just like Stu said you can always download the "driver" to your computer.

I don't have problems with interchanging the USB ports - I got scanner, 3 printers, digital camera, ipod, iphoto, wireless mouse, 300GB portable hard drive and 3 ports available for USB. I got 3 fire wire ports too.
