Since last night it was impossible to install a printer CANON PIXMA iP2000 and i was getting a constant error message that "USB Device Not recognized" on my Vista Home OS. The printer is connected via USB and I even tried to install the drivers from the CANON utility cd but again it was giving me error saying that "unknown device software has been installed correctly". I checked device manager and an "unknown device" was listed, but from there when i tried to load the drivers i got this message "the best driver for your device is already installed". Please help
