But HP's software indicates in cd's cover clearly "hp scanjet 3900 series" and as I can see, driver sends different parameters to rts8822 chipset depending on ccd type (toshiba or sony) and depending on usb version (1.1 or 2.0) so I think it covers the most options needed in other scanners managed by this chipset.
