I'd like to get a Canon S-100 digital still camera, but read the Canon's USB interface is not compatible with "upgrade" Windows versions - only works with "original" Windows op systems (installed by manufacturer??) System is older Dimension (300 MHz, 128MB, born 12-97), but it does all I need to do, including digital video thru firewire. Just upgraded to 98SE and installed a Logitech mouse on USB - everything works fine. Since the USB mouse works, is it likely the Canon USB will work also?
